During athletics day at school, a learner broke a record by running 800 m in 1 minute and 49 seconds. He ran 800 m in the following manner: first, he ran 300 m west and then 500 m southwest.

If the learner was running at a constant speed throughout the route, calculate the time the learner took to run the first 300 meters.

Answer :

Final answer:

The student took approximately 40.9 seconds to run the first 300 meters of the total 800 meter race, assuming he ran at a constant speed.

Explanation:

In this question, we are asked to find out the time taken to run the first 300 meters if the entire 800 meters was run in 1 minute and 49 seconds.

If we assume that the learner ran at a constant speed, we can say that the speed is the same over the entire distance.

Hence, the ratio of the distance covered to the total distance is equal to the ratio of the time taken for that distance to the total time.

Hence, time for 300m = (300/800) * 109 seconds (since 1 minute 49 seconds is 109 seconds in total) = 40.875 seconds.
