Step-by-step explanation:
Identify the variation and solve. It takes 5 hours to travel from one town to the other if speed of the bus is 48 km/hr. If the speed of the bus is reduced by 8 km/hr, how much time will it take for the same travel?
Let say Distance between Towns = D km
Speed of Bus = 48 km/hr
Time taken by Bus = 5 Hr
Distance = Speed * Time
=> D = 48 * 5
=> D = 240
Distance between towns = 240 km
Speed reduced by 8 km/hr
Reduced Speed = 48-8 = 40 km/Hr
Time Taken with reduced speed = 240/40 = 6 hr
it will take 6 hr for the same travel
Variation = 6- 5 = 1 hr ( 1 hr extra taken)
