Jason and Marie both travel 300 miles. Jason drove at an average speed of 10 miles per hour faster than Marie and made the trip in one hour less time. Find the average speed of both cars. Jason's speed = Marie's speed =
Added by Nancy K.
Step 1
According to the given information, Jason's speed is 10 miles per hour faster than Marie's speed, so Jason's speed is (x + 10) miles per hour. We know that both Jason and Marie traveled 300 miles, so we can use the formula: Time = Distance / Speed For Marie, Show more…
