Question

A car travels 90 km in 2.5 hours a) how much time is required to cover 30 km with same speed? b) find the distance covered in 2 hours with same speed?.

Answer 1

time = speed × distance
= 90km = 9000m/2.5 hours × 30
= 9000m/9000seconds×30
= 30 m = 30×60 = 1800 seconds.
distance = speed × time
= 9000/9000 × 3600 seconds
= 1×3600
distance = 3600 m
