Answer 1

If the odometer of a carreads 0 km at the beginining of a trip, and reads 45 km 30 minutes later what
is the average speed of the car?
V_av=S_total/T_total
V_av - the average speed
S_total - the total distance
T_total - the total time
V_av = 45 km / 30 minutes = 45 km / 0.5 hours =45/0.5 km/h = 90 km/h
