Question 11
Ted’s grandfather used his treadmill on $3$ days this week. He went $2$ miles each day.
On Monday he jogged at a speed of $5$ miles per hour. He walked at the rate of $3$ miles per hour on Wednesday and at $4$ miles per hour on Friday.
If Grandfather had always walked at $4$ miles per hour, he would have spent less time on the treadmill. How many minutes less?
