Question

a car travels 90 km in 5/2 how much time is required to cover 30 km with the same speed

Answer 1

Here is the answer to your question.

Distance traveled by the car = 90 km

Time taken by the car =hours = 2 hours + 30 minutes = 120 minutes + 30 minutes = 150 minutes

Speed of the car
=Distance travelled/Time taken
=90/150=3/5Km/min 

Time taken by the car to travel 30 km
=  Distance/speed
=30/(3/5)
=30×5/3
=50 minutes

Distance traveled by the car in 2 hours or 120 minutes = Speed × Time
=3/5×120
=72km

Time taken by the car to travel 30 km

=  Distance/speed

=30/(3/5)

=30×5/3
