If the bicyclists is traveling 18 miles every hour and needs to travel a sum of 90 miles, you need to divide 90/18 equaling the total time (in hours) needed to travel 90 miles. Hope this helps

musickatia [10]

5 - 6 = -1

-1 - 9 = -10

-10 - 8 = -18

-18 - 5 = -23

-23 - 4 = -27

-27 + 5 = -22

-22 - 5 = -27
