Question

The ratio of speed of 3 cars is 2:4:3 find the ratio of time taken by them

Answer 1

Answer:

6:4:3

Step-by-step explanation:

Let the speed of three cars be = S1,S2 and S3.

Similarly,  time can be denoted as = T1,T2,T3

Distance will be denoted as =  D1,D2,D3

Since, the speeds of three cars are in a ratio 2:3:4.

Thus, S1=2S, S2=3S and S3=4s.

Distance is the same - D1=D2=D3=D.

Time = Distance/Speed

Therefore, T1:T2:T3 = D1/S1 : D2/S2 : D3/S3 = D/2S : D/3s : D/4s

= 6:4:3.

Ratio of the time taken by cars will be 6:4:3.
