Answer:
Resultant velocity of the airplane = 80.62 km/h
Step-by-step explanation:
Given that,
An airplane normally flying at 80 km/h north encounters a wind from the west of 10km/h at right angle to its forward motion a crosswind.
We need to find the resultant velocity of the airplane. It can be calculated as follows :
So, the required velocity is 80.62 km/h.
