+545 To travel a given distance, the rate is inversely proportional to the time required. Tom noted that if he drove home at 100 kph, the trip would take 5 hours. How many hours would it take him to drive home if he drove at 125 kph? Do not use units in your answer.

R = k (1/T) where k is the proportionality constant.....we need to find this
100 = k (1/5) multiply both sides by 5
500 = k
At 125mph, we have
125 = 500(1/T) multiply both sides by T, divide both sides by 125
T = 500/125 = 4
