Question

Ms Davis runs at 6 1/2 miles per hour. The park is 7 3/4 miles from her house. How long will it take for her to run from home to the park and back home?

Answer 1

Answer:

Step-by-step explanation:

Speed V = 6 1/2 = 13/2 miles/hr

Distance d = 7 3/4 = 31/4 miles

Time t = ?

V = d/t

Cross Multiply

Vt = d

t = d/v

t = 31/4 ÷ 13/2

t = 31/4 × 2/13

t = 31/(2×13)

t = 31/26

t = 1 5/26 hours

One hour, 11 minutes, 32 seconds
