A student determines the speed of three remote-controlled model boats on a straight canal. The student measured the time for each boat to travel a distance of 60 m60\text{ m}60 m.
The table below shows the measurements:
| Boat | Distance travelled (m\text{m}m) | Time taken (s\text{s}s) |
|---|---|---|
| P | 60 | 15.0 |
| Q | 60 | 12.0 |
| R | 60 | 20.0 |
Without calculation, identify the fastest boat and the slowest boat.
Calculate the speed of boat P.
Estimate the time, in minutes, for boat Q to travel 2400 m2400\text{ m}2400 m.
Explain why your estimate in (b)(i) may not be the same as the actual time taken for the boat to travel 2400 m2400\text{ m}2400 m.
