Question

emergency solve fast​

Answer 1

Answer:

3:5:6

Step-by-step explanation:

let the speeds be 3x , 5x , 6x

distance is constant . let distance be d

time = distance by speed

so time taken by 3 cars are 3x / d , 5x / d and 6x / d respectively

ratio of time taken by 3 cars is 3x / d : 5x / d : 6x / d

1 / d will be cancelled

x also will be cancelled

so ratio of time taken by 3 cars is 3:5:6
