a whale swims 200 miles in 5 days. Identify which equation could be used to find how many miles it swims in 16 days
To find how many miles the whale swims in 16 days, we can set up a proportion using the given information.
Let's assume that the number of miles the whale swims in 16 days is "x".
We know that the whale swims 200 miles in 5 days. So, our proportion becomes:
200 miles / 5 days = x miles / 16 days
To find the value of "x", we can cross-multiply and solve for it:
200 * 16 = 5 * x
3200 = 5x
Dividing both sides by 5:
x = 3200 / 5
x = 640
Therefore, the equation that can be used to find how many miles the whale swims in 16 days is:
x = 640 miles
