The average speed is the ratio between the distance and time.
the answer is A= 69.6 km/h
40 mph
If their velocities are equal, then the speed of each bus relative to the other is zero. A passenger on one bus could read a newspaper held up by a passenger on the other one.
If a passenger on a bus moving east sees a man standing on a curb from the passenger's perspective, the man appears to be moving west at a speed equal to the bus' speed.

The bus' average speed is 34.72 meters per second.
88.514Km/hr or 24.587m/s
Easy - 20 minutes is one-third of an hour, and the bus traveled 30km. Multiply that 30km by three and that gives the total distance it would travel in one hour. Answer is an average speed of 90kmh.
Speed = distance/time so it is 450/5 = 90 km per hour.
Total Speed - 178.km Time - 2.5 Hrs Avergage Speed 71.2 Km h-1
It is 260 miles.
The average speed of the bus would be 90 km/h (450 km divided by 5 hours).
The average speed for both men (together) is 6.66... (repeating) km per hour.
