Question

an airplane travels 780 miles in 4 hours. what is the constant proportionality that represents the miles (y) and the hours (x)

Answer 1

The constant proportionality that represents the miles (y) and the hours (x) is the rate of the airplane, which is the ratio of the distance traveled to the time taken. To find the rate, we can use the formula:

rate = distance / time

Plugging in the given data, we get:

rate = 780 / 4

rate = 195

Therefore, the constant proportionality is 195, which means that the airplane travels 195 miles per hour.
