The number of planes arriving A at an airport during H hours can be represented by A = 20H. Select whether each statement is true or false representing the same proportional relationship.

True/False: After 4 hrs, 75 planes arrived

True/False: After 6 1/2 hrs, 130 planes arrived

True/False: If 60 planes arrived, 3hrs have passed

True/False: Every 30 minutes, 10 planes arrive.

True/False: Everyday 400 planes arrive at the airport

C in the answer to this question

The answer is option 3. 60 planes arrive after 3 hours

As the proportionality equation shows; A=20H

When H=3

A=20*3

A=60
