Question

if a boy can walk 5 km in 2 hours, how long will he take to walk 7.5 km.

Answer 1

Step-by-step explanation:

As Speed = Distance/Time,

Speed of boy = 5/2

= 2.5 km/hr

With the same speed, he walks 7.5 km,

By the same formula,

Time = Distance/Speed

Time taken for 7.5 km = 7.5/2.5

= 3 hr

Therefore, the boy takes 3 hours to walk 7.5 km
