Question

At 1:00 p.m., the water level in a pool is 13 inches. At 1:30 p.m., the water level is 18 inches. At 2:30 p.m.,the water level is 28 inches. What is the constant rate of change

Answer 1

Hey!

Hope this helps...

Now to solve this question all we need is basic math...

We know the water level (at 1:00 pm) started at 13in and than 30mins later it rose by 5in (going to 18in). Now an hour has passed and the water level has rose by 10in (making it 28in in total).

So, using basic math we can see that every 30mins the water level rises every 5in, and the equivalent ratio (simplified) is MINS to INCHES, 6min : 1in

So...

The answer is: Every 6mins the water level rises by 1in (rounded to the most simplified form).

ELSE

The answer is: Every 30mins the water level rises by 5in

Answer 2

the pool water goes up 5 inches every half hour.
