The time t required to drive a certain distance varies inversely with the speed r. If it takes 2 hours to drive the distance at 30 miles per hour, how long will it take to drive the same distance at 35 miles per hour?

given that:- time=t, speed=r and let distance=d
we know that:- time=distance/speed
t = d/r
2 = d/30
D = 60 (total distance traveled in 2 hours)
t = 60/r
t = 60/35
t = 1.714 hours
