You drive 50 mph for 1 hr and 30 mins, which expression can be used to find how many miles you travel?
My teacher told me it was C but I still don't understand how he got it
A) 50x130
B) 50x90
C) 50x1.5
D) 50/90

Time of 1 hour, 30 minutes = 1%2630%2F60, or 1%261%2F2, or 1.5 hours
Distance = Speed x Time
With speed of 50 mph, and time of 1.5 hours,
Distance = 50 x 1.5 (CHOICE C)
