Q149
ArithmeticSpeed, Time & Distance
The speeds of three cars are in the ratio 2 : 3 : 4. The ratio between the time taken by these cars to travel the same distance is
- a.2 : 3 : 4
- b.4 : 3 : 6
- c.3 : 4 : 6
- d.6 : 4 : 3
Answer: (D) 6 : 4 : 3
Time = Distance ÷ Speed. For the same distance, time is inversely proportional to speed. So time ratio = $\frac{1}{2} : \frac{1}{3} : \frac{1}{4} = 6 : 4 : 3$.
