Question

15. A boy can run 70 m in 9 seconds. How much time does
he need to run 350 m at the same speed?​

Answer 1

Solution :-

➡ Speed of boy

$= \frac{70}{9}$

➡ since speed is same. Therefore,

➡ Let the required time be x.

$speed = \frac{350}{x} \\ \\ \frac{70}{9} = \frac{350}{x} \\ \\ x = \frac{350 \times 9}{70} \\ \\ x = 5 \times 9 = 45 \: sec$

➡Thus time he need is 45 second.
