Question

Gerard is riding his bicycle directly east. His maximum instantaneous velocity was 8 meters per second and his minimum instantaneous velocity was 0 meters per second. He covered 7.20 kilometers in 20.0 minutes. What is his average velocity for the ride?

A) 8 m/s
B) 6 m/s
C) 4 m/s
D) 0 m/s

Answer 1

Gerard's average velocity for the ride is 6 m/s.

Step-by-step explanation:

To find the average velocity, we need to calculate the total displacement and divide it by the total time taken. In this case, Gerard traveled 7.20 kilometers east in 20 minutes. Since velocity is displacement divided by time, we can convert kilometers to meters and minutes to seconds to get the correct units. Therefore, Gerard's total displacement is 7.20 km * 1000 m/km = 7200 m. The total time taken is 20 min * 60 s/min = 1200 s. Now we can calculate the average velocity by dividing the total displacement by the total time: 7200 m / 1200 s = 6 m/s.
