At a particular speed, a jumbo jet can travel its own length in 20 seconds. At this same speed, the jumbo jet taxied completely past a 710-foot-long hangar in 70 seconds, as shown. What is the length of the jumbo jet in feet?
r = rate
d = distance
t = time
r = d/t
r = 710/70
r = 71/7
d = rt
d = 71/7*20
d = 1420/7
So the length of the jet is 1420/7 feet.
