Explanation / Answer

1 mile in 25 min means a speed of 1/25 miles per min

We know 26.8 miles per minute = 1 mph

1/25 miles per minute = 1/(26.8*25) = 0.0015 mph

As surface is flat, Grade G = 0

Energy cost = (S*0.1) + (S*G*1.8) + 3.5 = 0.1/25 + 0 + 3.5 = 3.504 ml.Kg^-1.min^-1

Divide by 3.5 = approx 1 MET

1 MET = 1 Kcal . Kg^-1. Hr^-1

1 MET = 60 Kcal . Kg^-1. Hr^-1
