Question

Jada's house is 3 and 2/5 miles from the library. Solve the equation to determine how long it will take her to walk from her house to the library if she walks at a steady speed of 4 miles per hour.

Answer 1

Time = distance / speed

Time = 3 2/5 miles / 4 miles per hour

Time = 17/5 / 4

Time = 17/5 x 1/4 = 17 x 1 / 5 x 4 = 17/20 hours

17/20 hours x 60 minutes per hour = 51 minutes.
