The answer is Isosceles triangle
For this question we will use the following relations.
100 centimeters=1 meter (or 1 centimeter= 0.01 meter)
10 millimeter=1 centimeter (or 1 mm=0.1 cm)
60 minutes = 1 hour (or 1 min=
hour)
Now, Jackson's speed is 1350 meters per hour. This can be converted to cm per minute as follows:
...Equation 1
Likewise, Jonah's swim speed in cm/min can be calculated as:
...Equation 2
As we can see clearly after comparing Equation 1 and Equation 2, Jonah's swim speed of 7500 cm/min is faster than that of Jackson.
Thus, option B is correct.
Let
be the unknown number. So, three times that number means
, and the square of the number is 
We have to sum 528 and three times the number, so we have 
Then, we have to subtract this number from
, so we have

The result is 120, so the equation is

This is a quadratic equation, i.e. an equation like
. These equation can be solved - assuming they have a solution - with the following formula

If you plug the values from your equation, you have

So, the two solutions would be


But we know that x is positive, so we only accept the solution
