Step 1: Find the distance traveled, convert any units needed
The distance traveled is 75,000 meters.
Step 2: Find the time taken to travel this distance, convert any units needed
The car traveled for 2 hours but this must be converted to seconds.
(2 hours) x (60 minutes) x (60 seconds) = 7,200 seconds in 2 hours
Step 3: Find the average speed by dividing the distance traveled by the time
75,000 meters ÷ 7,200 seconds = 10.42 m/s
