Answer - C. Explanation. Remaining work = (1- 2/5 ) = 3/5 , Remaining period = (56 – 30) =26 days. Let the additional men employed be x. More work , more men (direct) More days , less men (indirect) More hrs/ day, less men (indirect) Work 2/5 : 3/5 Days 26: 30 :: 104 : (104 + x) Hrs/ day 9:8 ∴ 2/5 *26 * 9 * (104 +x ) = 3/5 *30 * 8 * 104 ⇒ (104 +x) = 3 * 30 * 8 * 104 / 2* 26 * 9 = 160 ⇒ Someone aiming to complete their marathon under 3:30 will need to run approximately 90 kilometers (56 miles) per week at the peak of their marathon prep. For reference, professional marathoners run around 160 kilometers or 100 miles per week consistently! They also fit in time for strength training, stretching, dedicated recovery time and more! Pace table for speeds in kilometres per hour. These tables are particularly useful for those training on a treadmill, where speed in either miles per hour or kilometres per hour is typically displayed rather than pace. Many runners find it encouraging to note how small improvements in speed can result in significant changes in finish times. The time it takes to complete a 5k depends entirely on how fast you can walk. If you’re just starting, it might take you anywhere from 45 minutes to an hour and a half to complete the distance. Walking 3.1 miles will take 45 minutes to 1 hour for most people. Those who are used to walking at a fast pace and want to push themselves might be Most of the beginners take about 30–35 mins or more. I started taking part in weekly 5K runs in London and analyzed the results after each run. Here’s what I found. The best I saw (2 to 3 Bike: 90km (56 miles) Run: 21km (13.1 miles) Average finish times: 4-8 hours. How much time will you need to train: 7-13 hours per week. Total distance for a half is a 1900 meter swim, a 90 km bike and then a half marathon, 21.1 kilometers. Pro triathletes will be doing half triathlon in about three hours and 45 minutes. 440ICr. Conceived to convert 5K times into "minutes per mile" and "miles per hour", I have generalized this to any combination of distance and time, in miles or km. Enter the distance, choose the units, and your time in mm:ss format and hit TAB. Distance problems are word problems that involve the distance an object will travel at a certain average rate for a given period of time. The formula for distance problems is: distance = rate × time or. d = r × t. Things to watch out for: Make sure that you change the units when necessary. For example, if the rate is given in miles per hour 3 mph: ~ 1 hour (62 minutes) 3.5 mph: 53 minutes; 4 mph: 47 minutes; How Many Steps is a 5k? Your step count would depend on your step length (based on your height and stride) and speed. See our post for a complete table on how many steps there are in a mile. Steps in a 5k by height (estimated) 5’5″ – 7,195 steps; 5’8″ – 6,875 steps If you’re running at speeds under 9 miles an hour (a very fast 6:40-minute-mile pace), treadmill running burns about the same calories as outdoors. But if you run faster than nine mph, you’ll burn fewer calories on the treadmill. First, 5 kilometers is a distance, so . d = 5. Next, we are given 20 minutes and we are asked to present the speed in kilometers per hour rather than kilometers per minute. We need to convert 20 minutes to hours. Since there are 60 minutes per hour, we divide by 60 to find out how many hours it took. t = 20 minutes / 60 minutes per hour = 1/3 hours 10K Pace Chart. Getting ready to run a 10K? The table below will translate your goal finish time into your per mile or per kilometer pace, and will show your halfway split too. It also shows the splits for every 2 miles. If you need to see every mile, click the finish time at the start of the row. The rows start with Joshua Cheptegei’s world
