Answer:
distance=speed × time
d = 48×5
d= 240 km
reduced speed=48-8 km/h
New speed = 40km/h
speed=distance/time
40=240/t
t=240/40
t= 6 h

Answer:
The speed of the bus varies inversely with the time required to travel from one town to the other. where, k is the constant of variation. ∴ When v = 40, t = ? ∴ The problem is of inverse variation and the bus would take 6 hours to travel the distance if its speed is reduced by 8 km/hr.
