Answer:
4:5
Step-by-step explanation:
A bus covers 128 km in 2 hours.
Speed of the bus = distance / time = 128 km/ 2 hr = 64 km/hr.
A train covers 240 km in 3 hours.
Speed of the train = distance / time = 240 km/3 hr = 80 km/hr.
Ratio of theirs speed = 64 : 80 = 64/80 = ( 64 / 16) / (80 / 16) = 4/5
The ratio of the speed of bus and train = 4:5
