Answer 2

Answer:

All we need to know is relation between speed, distance and time.

Speed=distance / time

And the answer is

Step-by-step explanation:

speeds of 3 cars are S1, S2, S3 which are in ratio 2:3:4

so,

1. S1:S2:S3 = D1/T1:D2/T2:D3/T3

Here, D1= D2 = D3 = D

so, S1:S2:S3 = 1/T1:1/T2:1/T3

T1:T2:T3=1/S1:1/S2/:1/S3

=1/2:1/3:1/4

=6:4:3
