Answer:
The air speed of the plane is 90 km/hr. and the wind has a speed of 15 km/hr.
Step-by-step explanation:
The plane travels 720 km in 6 hours in the direction of the wind and it takes 8 hours to make the round trip.
If we assume that the speed of the plane is u km/hr. and that of wind is v km/hr.
Therefore, we can write ........ (1)
And ..... (2)
If we add those two equations, then 2u = 210, ⇒ u = 105 km/hr.
Again from equation (2), we get v = u - 90 = 105 - 90 = 15 km/hr.
Therefore, the airspeed of the plane is 90 km/hr. and the wind has a speed of 15 km/hr. (Answer)
