Question

The great seto bridge in japan is 9368 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?

Answer 1

74.944 minutes ( or around 75 minutes)

Explanation:

We know the distance formula:

D = RT

Where

D is the distance

R is the rate

T is the time

For Bicycle Ride:

R = 500 m/min

D = 9368 m

So,

T = D/R = 9368/500 = 18.736 minutes

For Walking:

D = 9368 m

R = 100 m/min

So,

T = D/R = 9368/100 = 93.68 minutes

So, the difference is:

93.68 - 18.736 = 74.944

The bicycle trip is about 74.944 minutes shorter than the walk.
