The length of the treadmill in the stadium is 700 m. The athlete runs it in 1 minute 40 seconds. What distance will the athlete run in 30 minutes if he moves at the same speed?
1. It is known that the distance is equal to the product of the speed and the time during which this distance is covered.
2. Find out the speed of an athlete if, according to the condition of the problem, he runs 700 meters in 1 minute 40 seconds.
700 m: 1 m 40 sec. = 700 m: 100 sec. = 7 m / s = 7 m / s * 60 = 420 m / min.
3. Determine the length of the path that the athlete will run in 30 minutes.
420 m / min. * 30 minutes = 12600 meters = 12 km 600 m.
Answer: The athlete will run 12 kilometers 600 meters.
