Final answer:
Josh's average speed for his 4-hour cycling trip is calculated as 31 km/h, which is found by dividing the total distance of 124 km by the total time of 4 hours.
Step-by-step explanation:
Josh's average speed is calculated by dividing the total distance cycled by the total time taken to cycle that distance. In this case, Josh cycles a distance of 124 km in a time span of 4 hours. To find the average speed, we use the formula:
Average Speed = Total Distance ÷ Total Time
Plugging the values into the formula, we get:
Average Speed = 124 km ÷ 4 hours = 31 km/h
So, Josh's average speed during his 4-hour cycling trip is 31 kilometers per hour (km/h).
