An airplane travels 780 miles in 4 hours. make a table and graph to show the mileage for 2,8 and 12 hours. is there a direct variation? explain.

Yes, there is a direct variation, where the constant is 195 miles\hr

Step-by-step explanation:

Consider the provided information.

An airplane travels 780 miles in 4 hours.

780 miles = 4 hours

Divide both the sides by 4.

780/4 miles = 4/4 hours

195 miles = 1 hours

we need to make a table and graph to show the mileage for 2,8 and 12 hours.

The required table is shown below:

hr        Mileage (Miles)

2         2×195 = 390 miles

8         8×195 = 1560 miles

12       12×195 = 2340 miles

From the table we can observe that there is a direct variation, where the constant is 195 miles\hr

The graph of the table is shown below.

The graph is a line passing through the origin.
