Question

Direction (87-91): The table given below shows the data about track record of car racing game, where 4 cars P, Q, R and S are competing to reach finishing line which is at a distance of 3000 m from their initial starting point. 1. Drift refers to over starting intentionally done by driver. 2. While calculating average speed, do not consider time taken in drift/crash. 3. Points = 50 × drifts - 20 × crashed Cars | Drift | Time to reach finishing line (in sec) | Crash P | 5 | 180 | 3 Q | 7 | 120 | 5 R | 6 | 150 | 4 S | 8 | 100 | 6 Speed of car S is what percentage more than that of car Q?

Accepted Answer

20%. Speed is distance divided by time, and both cars cover the same 3000 m. Car S moves at 30 m/s while car Q moves at 25 m/s, so S is 20% faster than Q.
