I think you forgot to put the pictures-
V = 7 x 4 x 15 = 420 inches^3
48.012001 is the answer to this problem

55 miles is 290400 feet so you are driving at 290400 feet per hour now there are 60 minutes In an hours so divide
290400/60=4840
4840 feet per minute
there are 60 seconds in a minute so divide again
4840/60=80.67
80.67feet per second rounded
