The Great seto Bridge in Japan is 9,368 meters long. A bicyclist riding across the bridge can travel 500 meters in 1 minute. A person walking can travel 100 meters in 1 minute. How many minutes shorter is the bicycle trip than the walk?

(bike time)  (walking time)
= 9368/100  9368/500
= 74.9 min 
Thank you this is not an answer
