A whale swims 200 miles in 5 days. Identify which equation could be used to find how many miles it swims in 16 days.(1 point)
Responses

200=16x
200 equals 16 x

y=200×16×5
y equals 200 times 16 times 5

y=40×16
y equals 40 times 16

Answer 1

To find out how many miles a whale swims in 16 days based on the information that it swims 200 miles in 5 days, we first need to determine the rate of swimming per day.

The rate of swimming per day is calculated as follows:

\[
\text{Rate} = \frac{200 \text{ miles}}{5 \text{ days}} = 40 \text{ miles per day}
\]

Now, to find out how far the whale swims in 16 days, we can multiply the daily rate by the number of days:

\[
\text{Distance in 16 days} = 40 \text{ miles/day} \times 16 \text{ days} = 640 \text{ miles}
\]

Thus, the equation we could use to represent this situation is:

\[
y = 40 \times 16
\]

So the correct response is:

**y = 40×16**
y equals 40 times 16
