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

To determine how many minutes shorter the bicycle trip is than the walk, we first need to calculate the time it takes for each mode of transportation to cross the Great Seto Bridge.
For the bicycle trip, we know that the bridge is 9,368 meters long, and the bicyclist can travel 500 meters in 1 minute. So, the time it takes for the bicyclist to cross the bridge can be found by dividing the length of the bridge by the distance covered in one minute:
Time for bicycle trip = Length of bridge / Distance covered in 1 minute
Time for bicycle trip = 9,368 meters / 500 meters per minute
Time for bicycle trip = 18.736 minutes (rounded to three decimal places)
For the walking trip, we know that the person can travel 100 meters in 1 minute. So, the time it takes for the person to cross the bridge can be found by dividing the length of the bridge by the distance covered in one minute:
Time for walking trip = Length of bridge / Distance covered in 1 minute
Time for walking trip = 9,368 meters / 100 meters per minute
Time for walking trip = 93.68 minutes
Now, to find the difference in time between the bicycle and walking trips, we subtract the time for the bicycle trip from the time for the walking trip:
Difference in time = Time for walking trip - Time for bicycle trip
Difference in time = 93.68 minutes - 18.736 minutes
Difference in time = 74.944 minutes (rounded to three decimal places)
Therefore, the bicycle trip is approximately 74.944 minutes shorter than the walk across the Great Seto Bridge in Japan.
