A) Max travels to see his brother's family by car. He drives 216 miles in 4 hours.
What is his rate in miles per hour? Use a double number line to show your work.
B) Suppose he makes two stops of 10 minutes each during his journey. Will he be
able to reach the town in 4 hours if he keeps the speed the same?

(also what is a double number line?)

Step-by-step explanation:

A double number line is two parallel number lines with the same number of division.

On the top number line, we show the increments in time, starting with 0 and going up by 1 until we get to 4.

On the bottom number line, we show the increments in distance, starting at 0 and going up by 54 until we get to 216.

So every hour, he travels 54 miles, meaning his speed is 54 mph.

If he makes any stops, it will take him longer to reach the town without changing his speed.

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed
