Question

Two students travel from school to their jobs at the bowling alley, which is 2.5 km away. One student rides a scooter at 9.0 m/s, and the other student rides a bike at 12 mi/hr. How long does the trip take for each of them?

Answer 1

The student on the scooter takes approximately 277.8 seconds, while the student on the bike takes about 466.4 seconds.

Step-by-step explanation:

The trip takes different amounts of time for the two students because they are traveling at different speeds. To calculate the time taken for each student, we can use the formula:

time = distance / speed

For the student on the scooter:

time = 2.5 km / 9.0 m/s

Converting the distance to meters:

time = 2500 m / 9.0 m/s = 277.8 seconds

For the student on the bike:

First, we need to convert the speed from miles per hour to meters per second:

speed = 12 mi/hr × 1609.34 m/mi / 3600 s/hr = 5.36 m/s

time = 2.5 km / 5.36 m/s = 466.4 seconds

Therefore, the trip takes approximately 277.8 seconds for the student on the scooter and 466.4 seconds for the student on the bike.
