11. Mary traveled a total of 10 hours and a total of 1850 miles by car and by plane Driving to the airport by car, she averaged 50 miles per hour. In the air, the plane averaged 300 miles per hour. How long

did it take her to drive to the airport?

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.

The correct answer is $90
