Question

The average velocity of a plane is 600 km/h. How long does it take the plane to travel 120 km?

a. 0.2 hour
b. 0.5 hour
c. 0.7 hour
d. 5 hours

Answer 1

You have to divide 120/600 which you will get 0.2 hours as your answer.

Hope this helps!

Answer 2

`\boxed {\tt A. \ 0.2 \ hour}`

Step-by-step explanation:

We can find time by dividing the distance by the velocity.

`t=(d)/(v)`

The distance traveled is 120 kilometers and the velocity of the plane is 600 kilometers per hour.

`d= 120 \ km \\v= 600 \ km/hr`

Substitute the values into the formula.

`t=(120 \ km )/( 600 \ km/hr)`

Divide. Note the kilometers, or
`km` will cancel each other out.

`t=(120 )/(600 \ hr)`

`t= 0.2 \ hr`

It will take 0.2 hours for the plane to travel 120 kilometers. Choice A is correct.
