Answer:
13 minutes
Step by step Explanation:
The time spent at treadmill = ( 2/3 ) of an hour = 40 minutes
The total time spent at gym = 1 3/4 of an hour = 105 minutes
Substituting the values in the equation , we get
5A + 40 = 105
On simplifying the equation , we get
Subtracting 40 on both sides of the equation , we get
5A = 65
Divide by 5 on both sides of the equation , we get
13 minutes
