Question:
By travelling at a speed of 48 kilometres per hour, a car can finish a certain journey in 10 hours. To cover the same distance in 8 hours, the speed of the car
should be
(a) 60 km/h
(b) 80 km/h
(c) 30 km/h
(d) 40 km/h
Solution:
(a) 60 km/h
Explanation: Speed of car = 48 km/hr
Time taken = 10 hr
As we know,
Distance = speed × time = 48 × 10 = 480 km
Speed required by car to cover 480 km in 8 hours = 480/8 = 60 km/hr.
