Answer:
100 miles per hour.
Explanation:
To solve this we need to divide 5 by 5 to find the answer for 1 hour rather than 5.
5 / 5 = 1
Following the logic of, “what you do to one side, you must do to the other” i will divide 500 by 5.
500 / 5 = 100
Mr B was traveling at 100 miles per hour.
(you should probably tell him to slow down haha)
