Answer:
5-mile
Step-by-step explanation:
In order to calculate the distance between the park and the school, which is marked by the x in the picture attached we need to use the Pythagorean theorem. This equation is the following

where a is the 3 miles east and b is the 4 miles south ... now we can plug in these values and solve the equation.
... square both the 3 and the 4
... add the two values
... square root both sides

5 = c
Finally we can see that there is a 5-mile distance between the park and the apartment
10/20 is the lowest fraction term
40x + 50x = 750
90x = 750
x = 750 / 90 = 8.333 hours
40 * 8.33 = 333.4
50 * 8.33 = 416.6
8.33 hours = 8 hours and 20 mintutes
they will meet at 7:20 pm
