प्रश्न
A car moves at a uniform speed of 75 km per hour. How much distance will it cover in 98 hours?
उत्तर
Uniform speed of a car = 75 km/h
Distance = speed × time
= 75 × 98
=75 × (100 − 2) (Using distributive law)
=75 × 100 − 75 × 2
=7500 − 150
= 7350 km
∴ The distance covered in 98 h is 7350 km.
