Answer:
384.6 m
Explanation:
The length of the runway airport should be long enough to accommodate the aircraft during its acceleration from rest to 161 km/h at rate of 2.6 m/s. We can use the following equation of motion to solve for this:
where v0 = 0 m/s is the initial velocity of the airplane when it start accelerating, v = 161 km/h = 161*1000*(1/60)(1/60) = 44.72 m/s is the airborn speed, a = 2.6 m/s2 is the acceleration, and 
is the distance of the runway, which we care looking for

So if a car was moving 40km/hr, it means in 1 hour, the car will travel 40km. Since the car goes for 2 hours, the car will have traveled for 80 miles. Same.for the car going 55km/hr for 2 hours. 55 times 2 is 110km. 110 + 80 = 190km total. You can find the average velocity by by the distance traveled divided by how much time elapsed. so 190 divided by 4 is 47.5. So the distance traveled is 190km, and the average velocity is 47.5
