distance to cool down if she runs at a speed of 9 mph and walls back at a speed of 3 mph, how long should she plan to spend láng bade

Answer 1

Answer:

running 1.5 hours

Walking 4.5 hours

Step-by-step explanation:

Let the amount of time she spends on walking be x

d/3 + d/9 = 6            Multiply by 9

3d + d = 6*9

4d = 54                     Divide by 4

4d/4 = 54/4            

d = 13 2/4 = 13 1/2 = 13.5 miles

d/3 = 13.5/3 = 4.5 hours

d/9 = 13.5/9 = 1.5 hours

Total                6 hours

I hope this is the right interpretation.
