Exercise 2 Page 185

We want to complete a table. We can use the portion where both values are known to find the missing values.

We know that we travel 52 kilometers in 4 hours. Let's write this as a ratio. 52kilometers/4hours or 52/4We will use this rate to find the missing values.

First Value

We can find an equivalent ratio with a denominator of 16 to find how many kilometers we travel 16 hours.

We can travel 10 kilometers in 16 hours.

Second Value

Now, we can find an equivalent ratio with a numerator of 5 to find how hours it takes us to travel 5 kilometers.

We can travel 5 kilometers in 8 hours.

The equivalent ratios are 52:4, 10:16, and 5:8.
