30 points! Find the rate of change.

A): 1/63; The car travels 1 mile every 63 hours.

B): 10; The car travels 1 mile every 63 hours.

C): 63/1; The car travels 63 miles every 1 hour.

D): 252; The car travels 252 miles.

The correct answer would be the fourth choice

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.
