Answer:
Given:
Time = 50 minutes
=》 50/60 hr
Speed = 45 km/hr
Distance = Speed × Time
=》 45 × 50 / 60
=》 37.5 km
Now,
In the second case:
Distance = 37.5 km
Speed = 30 km/hr
Time = Distance / Speed
=》 37.5 / 30
We can directly convert the time in minutes from hours by multiplying by 60. We will do this 5o simplify our calculation.
=》 37.5 × 60 / 30
=》 75 minutes.
