Question

If a boy can walk 5 km in 2 hours, how long will he take to walk.
0.25 km at this speed?​

Answer 1

The time is "6 seconds".

Step-by-step explanation:

Given,

Distance = 5 km, time = 2 hours

∴ Speed = $\dfrac{Distance}{Time}$

= $\dfrac{5 km}{2 hours}$

= 2.5 $\dfrac{km}{hr}$

Also,

Distance = 0.25 km

∴ Time = $\dfrac{Distance}{Speed}$

= $\dfrac{0.25}{2.5} hr$

=$\dfrac{1}{10} hr$

= 6 seconds

Hence, the time is "6 seconds".
