Patton's troops covered 48 miles in 4 hours. he then increased the speed by 8 miles an hour. if the total distance was 108 miles, then how long did it take to finish the trip?

Respuesta :

                               48 miles/4hrs = 12 mph

Increased Speed 12 mph + 8mph = 20 mph

Distance left        108 miles - 48 miles = 60 miles

Time left               60 miles/20 mph = 3 hours
