Question

13. A boy can run 70 m in 9 seconds. How much time
does he need to run 3580 m at the same speed?​

Answer 1

Let us find the speed that a boy can run

Speed = 70/9

Speed = 7.78 m/s

Since you have been limited to use the same speed, then

Time = 3580/7.78

Time = 460 m/s

Thus a boy can run 3580m in 460 seconds.

Answer 2

Answer:

1 second = 70/9

=7.7 sec.

How much time he take to cover 3580.

change 3580=35800 and 7.7=77

=. =35800/77

=. =460.29
