Answer 1

Step-by-step explanation:

Question:

Jim walks 3 miles in 87 minutes. Calculate speed per hour.

Answer:

1 mile = 1.609 km

3 miles = 1.609×3 = 4.827 km

1 hour = 60 minutes

1 minutes = 1/60 hour

87 minutes = 1/60 × 87 = 29/20 hour

Speed = Distance/Time = 4.827 ÷ 29/60 = 4.827× 60/29= 9.98km/hr. = 9.9 km/hr (approx).
