Question

a person travelled 750 km by train 440 km by bus 220 km by car it takes 25 hours in all if the ratio of speed of car 7:11 and ratio of the speed of bus to train is 11:25 what is the speed of bus​

Answer 1

Step-by-step explanation:

Let the speed of train, bus and train are 25k, 11k and 7k respectively

750/25k + 440/11k + 210/7k = 25

or, 30 + 40 + 30 = 25k

or, k = 4

Thus speed of bus = 11 × 4 = 44 kmph
