The table shows the relationship between the time and distance a car travels. What is the missing value?

9514 1404 393

  220

Step-by-step explanation:

When the relationship is proportional, there are several ways you can find missing values. One of them is to recognize the distance for 4 hours will be double the distance for 2 hours.

  2 hours : 110 miles

  4 hours : 2×110 miles = 220 miles

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
