Frank left his house at 7 a. m. and drove to the airport at a speed of 50 mph. Lance left his house at 6 a. m. and drove to the same airport at a speed of 55 mph. Frank's house is 150 miles from the airport and Lance's house is 220 miles from the airport.
At what time did Lance arrive at the airport?

10 AM

Step-by-step explanation:

Frank drove at a speed of 50 mph, and traveled a distance of 150 miles.  This means he traveled for

7 AM + 3 hours = 10 AM

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.
