A cyclist travels 120 km in 3 hours, rests for 1 hour, and then travels another 80 km in 2 hours. To determine the cyclist's average speed for the entire journey, which of the following quantities should be used?
Total distance travelled divided by the total time taken
Average speed is defined as the total path length covered divided by the total time taken, including any rest time.
It uses total distance, which is a scalar, not displacement or change in velocity.
Here total distance = 120 + 80 = 200 km and total time = 3 + 1 + 2 = 6 hours, so the quantity needed is total distance divided by total time.
Hence, the answer is total distance travelled divided by the total time taken.
