Answer 1

Question

A car covers a certain distance in 40 minutes, if it runs at 54 km/hr. How much time will it take to cover the same distance at a speed of 45 km/hr ?

Required Answer

It will take 0.8 hours to cover the same distance at a speed of 45 km/hr.

Step by Step Explanation:-

Given:-

${\pink{\dot{\circ}}}$A car covers a certain distance in 40 minutes.

To Find:-

${\pink{\dot{\circ}}}$How much time will it take to cover the same distance at a speed 45 km/hr ?

Solution:-

We know that,

60 minutes = 1 hour

1 minutes = $\sf{ \frac{1}{60}}$

Distance = 40 km

= $\sf{ \frac{40}{60}}$

Speed = 54 km/hr

= Speed × time

= 40/60 × 54

So,Distance = 36 km

So, time taken = 36/45

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Hence,it will be take 0.8 hours to cover the same distanceat a speed of 45 km/hr.
