Step-by-step explanation:

GIVEN

Time = 40 minutes = 0.6 hour

Speed = 54 km/h

___________________________

TO FIND

How much time it take to cover the same distance at a speed 45 km/hr

___________________________

We know that,

Speed = Distance / Time

Distance = Speed × Time

Time = Distance / Speed

___________________________

We know that,

Distance = Speed × Time

Distance = 54 × 0.6

Distance = 32.4

Distance = 32.4 km

___________________________

Now

Let's find How much time it take to cover the same distance at a speed 45 km/hr

We know that,

Time = Distance / Speed

Time = 32.4 km / 45

Time = 0.72

Time = 0.72 hours

Time = 43.2 minutes
