> Speed of the first runner = 750 / 150 = 5 m / sec We convert this speed to km/hr by multiplying it by 18/5. => Speed of the first runner = 18 km / hr Also, we are given that the speed of the second runner is 17.95 km/hr. Therefore, the first runner can beat the second runner. Q 2. A man decided to cover a distance of 6 km in 84 minutes. Amotorboat whose speed in still water is 5 km/h, takes 1 hour more to go 12 km upstream than to return downstream to the same spot. Find the speed of the stream. Let the speed of the stream be x km/hr. Then, speed downstream = (5 + x) km/hr. And, speed upstream = (5 – x) km/hr. Now, Time taken by the boat to cover 12 km upstream =. averagespeed = total distance / total time. Typical units are kilometers per hour (kph), miles per hour (mph), meters per second (m/s), and feet per second (ft/s). In Adistance of 1.4 Km is covered in 10 min , then speed=_____Km/min; A distance of 32 Km is covered in 1.6 hrs , then speed=_____Km/min; A and B start from the same point and at the same time with speeds 15 Km/h and 12 Km/h respectively . Find the distance between A and B after 6 hours if both move in: i)same direction ii) opposite Theaverage marathon finish time for men across all ages is 3:34:56. This is 8:12 per mile or 5:06 per kilometer. You would run 5.88 kilometers or 3.66 miles in 30 minutes at this pace. Lastly, with an average marathon time of 4:08:09 for women (9:28 min/mile or 5:53 per kilometer), women would run 3.17 miles or 5.1 km in 30 minutes. Forexample, if a car travels 100 miles in 1.5 hours and 20 miles in .5 hours, their total distance traveled would be 100+20 = 120 miles and their total time traveled would be 1.5 + .5 = 2 hours. Weare given that two thirds of the 6 km was covered at 4 km / hr i.e. 4 km distance was covered at 4 km / hr. Time taken to cover 4 km = 4 km / 4 km / hr = 1 hr = 60 minutes. Time left = 84 – 60 = 24 minutes. Now, the man has to cover remaining 2 km in 24 minutes or 24 / 60 = 0.4 hours. Speed required for remaining 2 km = 2 km / 0.4 hr = 5 Togain some perspective, an experienced cyclist could ride at 45kmp for a long time, and it would take around 4 minutes to cycle 5KM. So, for a cyclist with average fitness in good weather and fairly flat ground, 5 K should take around 15 minutes at a speed of 10 – 12 mph (ca. 19 km/h). Ifyou are running on a track, 5k in 17 minutes works out to 1:22 per 400 meters (82 seconds) and 2:44 for 800 meters. 5k in 17 Minutes Running Speed. If you are training to run 5k in 17 minutes on the treadmill, your race pace workouts will be run at a treadmill speed of 11 mph (slightly slower than 5:27 pace) or 17.6 km/hr. 5k in 17 3 Increase your mileage 10 to 15 percent every two to three weeks throughout this phase. For example, if you start at 50 miles per week -- on the low side for a sub-15-minute 5K runner -- you would be running 55 to 60 miles a week at the end of week three, 60 to 70 per week at the end of week six, 65 to 80 at the end of week nine, and 70 0C0fhP.
