60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles

part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles

total is 180mi+140mi=320miles
320 is what i think ecause 60 times 3 equals 180 and 70 times 2 equals 140 and 180 plus 140 equal
