Question

A plane is traveling toward the east with a velocity of 120 km/h. It encounters a wind blowing toward the east at 0.20 km/min. What is the velocity of the plane in km/h?

a) 120.20 km/h
b) 119.80 km/h
c) 120.40 km/h
d) 119.60 km/h

Answer 1

To determine the velocity of the plane relative to the ground, we add the velocity of the plane and the velocity of the wind, which results in a velocity of 132 km/h.

Step-by-step explanation:

To determine the velocity of the plane relative to the ground, we need to consider the effect of the wind. The plane is traveling toward the east with a velocity of 120 km/h, and it encounters a wind blowing toward the east at 0.20 km/min. We need to convert the wind velocity to km/h in order to add it to the velocity of the plane.

First, we convert the wind velocity from km/min to km/h:

0.20 km/min * 60 min/h = 12 km/h

Now, we can add the velocity of the plane and the velocity of the wind:

120 km/h + 12 km/h = 132 km/h

Therefore, the velocity of the plane relative to the ground is 132 km/h.
