Question

The speeds of three cars are in the ratio 2:3:4. What is the ratio of the time taken by these cars to travel the same distance

Answer 1

Answer:

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.

Answer 2

T is inversely proportional to v

So ratio of t= 4:3:2
