It takes a bus driver 30 minutes to pick up students from four stops. The last stop is at the corner of Green Street and Route 70. The most direct route to school is north on Route 70. The speed limit on Route 70 is 35 kph. The bus driver wants to calculate the average velocity from the last stop to school.
Can this be done from the information given?
No, the distance from the last stop to the school and the time it takes to travel that distance are required.
No, the distance from the first stop to the school and the average speed are required.
Yes, if the average speed is 35 kph, and it takes 30 minutes, the average velocity is 17.5 kph.
Yes, if the speed limit is 35 kph, and the elapsed time is 30 minutes, the average velocity is 17.5 kph north
