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
