A person takes a trip, driving with a constant speed of 92.0 km/h except for a 22.0 min rest stop. If the person's average speed is 78.6 km/h, how long is the trip?

Answer 1

Average speed =total distance/ time taken
V=(v•t+tₒ)/(t+tₒ)

v=92 km/h =25.6 m/s.
V=78.6 km/h =21.8 m/s
tₒ=22 min=1320 s.
Plug in data and solve for ’t’
