Kira is going for a walk. She walks at a speed of 3 miles per hour for 7.5 miles. For how many hours does she walk?
Answer provided by our tutors
The following information is given:
v = 3 mph Kira's average speed
d = 7.5 mi the distance she walks
We need to find t, the time in hours.
Since v = d/t we have:
3 = 7.5/t
7.5/t = 3
........
click here to see the equation solved for t
........
t = 2.5 hr
t = 2 hr 0.5*60 min
t = 2 hr 30 min
Kira walks 2 hours and 30 minutes.
