Question 989271
Jennifer flew to Las Vegas averaging 240 miles per hour. She flew back home averaging 210 miles per hour. If she spent a total of 12 1/2 hours traveling to and from Las Vegas, what is the distance from Jennifer's home to Las Vegas?
--------------
Avg speed of the round trip = 2*240*210/(240+210)
= 100800/450
= 224 mi/hr
-------------------
RT distance = 12.5*224 = 2800 miles
---> 1400 miles each way
