Answer:
Speed of train = 28.8 km/h
Explanation:
Given that,
Speed of car = 24 km/h
We need to find the speed of train.
Speed of train is 20% more than speed of car.
Speed of train = Speed of car + 20% of speed of car
= 24 + 0.20 x 24
= 24 + 4.8
= 28.8 km/h
Hence, The speed of two train would be 28.8 km/h
