Jenny and Bella are planning a road trip. Their total distance is 381 miles. If they drive at an average speed of 60 mph, how long will the two be in the car for?

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)
If we then divide that by average speed, we get the equation for time given average speed and distance traveled:
(distance traveled) / (average speed) = time
The average speed is 60 mph
The distance traveled is 381 miles
If we plug in the numbers we get:
Time = 381 miles / 60 mph = 6.35 hours
