The time, t, required to drive a certain distance varies inversely with the speed, r. If it takes 7 hours to drive the distance at 55 miles per hour, how long will it take to drive the dame distance at 65 miles per hour?
about 6.25 hours
about 385.00 hours
about 5.92 hours
about 3.21 hours

the term "varies inversely" means that the more speed you have, the less time it take

if you are driving 7 hours at 55 miles per hour, then you are driving a total of 385 miles. now if we change the speed to 65 miles per hour, we can find out the new time by dividing the total distance by the new speed (65)

so the answer would be 385/65 = new number of hours
