Question:

Emily takes a trip, driving with a constant velocity of 90 km/h to the north except for a 30 min rest stop. If Emily's average velocity is 75 km/h to the north, how long does the trip take?

Akanksha A.
Answer:

The average velocity is the ratio of traveled distance and the traveled time: v= L/t=75 If the traveled time is t, then Emily traveled time (t-0.5)h with the speed 90 km/h. Then the traveled distance is: L= 90*(t-0.5) We substitute this relation in the first equation and obtain: 75t= 90*(t-0.5) So, t=0.33h= 19.8 mins Then we can find L (length of the trip): L=24.8 km.
