Question

Ratio of speed of 3 cars is 2:3:4 the ratio of time taken these cars to travel the same distance is how much

Answer 1

Step-by-step explanation:

Let's denote speed of 3 cars as S1,S2 and S3. Same way, time and distance can be denoted as T1,T2,T3 and D1,D2,D3 for respective cars.

The speeds of 3 cars are in a ratio 2:3:4. ==> S1=2S, S2=3S and S3=4s.

Distance is same. ==> D1=D2=D3=D.

SPEED=DISTANCE/TIME TAKEN.

So, T1:T2:T3 = D1/S1 : D2/S2 : D3/S3 = D/2S : D/3s : D/4s = 6:4:3.
