Answer:
10 miles
Step-by-step explanation:
3.75 miles in 1.5 hours
=> 1.25 miles in 0.5 hours (divided by 3)
=> 10 miles in 4 hours (multiplied by 8)
Alternatively, the speed is
speed = distance / time = 3.75 / 1.5 = 2.5.
Rearranging the formula, we have that in 4 hours, she walks
distance = speed × time = 2.5 × 4 = 10.
