Race day has finally arrived, and the event is about to begin. Each racer must complete one lap on the circular track, which has a radius of 15 meters. You find yourself racing against Ali Al Jouda! He holds the record for the KSAA U14 100m race. You are worried but motivated! According to his record, he runs at an average speed of 8.4 m/s. Your average speed is 7 m/s. How far will you have run by the time Ali crosses the finish line?

78.54 meters

Step-by-step explanation:

circular path

radius = 15 meters

First we have to calculate the circumference of the circular path = 2

= 2 *

= 94.285 meters ( total distance to be covered )

For Ali running at a speed of 8.4 meters/ seconds

It will take him : ( 94.285 / 8.4 ) seconds

= 11.22 seconds

You running at a speed of 7 meters/seconds

hence at 11.22 seconds when Ali must have crossed the finish line you must have covered ;

(11.22 * 7 ) meters

= 78.54 meters

3: 2
