Answer 1

Question:-

A truck travels a certain distance at the speed of 40km/hr in 5hrs. what should be the speed of truck if it wants to travel the distance in 4hrs?

Given:-

• A truck travels certain distance at a speed of 40km/hr in 5 hours.

Solution:-

$\tt\implies \: Distance = Speed \times Time$

$\tt\implies \: Distance = 40 \times 5$

$\tt\implies \: Distance = 200 km$

Now ,

We have to find the speed if it travels 200 km in 4 hours:-

$\tt\implies \: Speed = \dfrac{ Distance } { Time }$

$\tt\implies \: Speed = \cancel\dfrac{ 200 } { 4 }$

$\tt\implies \: Speed = 50 km/hr$
