Question

Quizplus · Accepted Answer

The equation for average speed is:
Average speed = distance traveled / time
If we multiply both sides by time we get the equation for distance traveled given average speed and time:
Distance traveled = (average speed) x (time)
The average speed is 65 mph
The time is 4.5 hours
If we plug in the numbers we get:
Distance traveled = (65 mph)(4.5 hours) = 292.5 miles
