Terry drove 310 miles in 5 hours at a constant speed. how long would it take him to drive 403 miles at the same speed

Take 310 and divide it by 5 to get Miles per Hour then divide 403 by the number you found (should be 62) to get the amount of hours need to travel 403 miles. So altogether you do 310 divided by 5=62 then 403 divided by 62=6.5 hours to travel 403 miles.
