Distance = Speed * Time

Speed = Distance / Time

Time = Distance / Speed

Speed = 16km / (13min/ 60 min) --> 60min = 1hr (your statement)

Speed = 16km/1 * 60/13

(Division by a fraction is done by multiplying the dividend by the reciprocal of the divisor, in accordance with the identity)

Speed = 960 / 13 (simplify)

Speed = 73.84615385 km/hr (solution)

Speed = Distance / Time

Time = Distance / Speed

__The Problem____Apply the above formula: Speed = Distance / Time__Speed = 16km / (13min/ 60 min) --> 60min = 1hr (your statement)

Speed = 16km/1 * 60/13

(Division by a fraction is done by multiplying the dividend by the reciprocal of the divisor, in accordance with the identity)

Speed = 960 / 13 (simplify)

Speed = 73.84615385 km/hr (solution)
