WebSolution: Consider speed as m and time parameter as n. If the time taken increases, then the speed decreases. This is an inverse proportional relation, hence m ∝ 1/n. Using the inverse proportion formula, m = k/ n. m × n = k. At speed of 60 miles/hour, time = 3 hours, from this we get, k = 60 × 3 = 180.
