Question

A boy running at a uniform speed of 4.5m/s. How much time will he take to cover a distance of 2.25km?​

Answer 1

Answer:

Given,

speed = 4.5 m/s

time = ?

Distance = 2.25 km = 2250m

Speed = Distance/Time

4.5 = 2250/Time

Time = 2250/4.5

Time = 500 s = 25/3 hr.

Answer 2

Answer:

Explanation:

Answer is 500 seconds.

speed (v) = 4.5m/s

Distance (s) = 2.25 km = 225×10^3

Time is taken (t) = ?

V = s/t

t = s/v

= 2.25× 10^3/ 4.5

= 2250/ 4.5

= 450/ 0.9

= 500 seconds
