You can put this solution on YOUR website! A man gets a call from his wife saying that she is 60 miles from home with a flat tire. She is heading towards home at 20 mph on the donut spare. If he drives to meet her with the full sized spare how fast must he drive to get to her in 45 minutes?
--------
Her DATA:
rate = 20 mph ; time = 3/4 hr ; distance = (3/4)20 = 15 miles
---------------------
His DATA:
rate = x ; time = 3/4 hr ; distance = 60-15 = 45 miles
----------
Equation:
rate*time = distance
x(3/4) = 45
x = (4/3)45
x = 60 mph ( rate required to meet her in 3/4 hr)
