The pool leaks 7/8 of a gallon in 1/2 hour. Times that by 2 to find out how many gallons per hour. 7/8 x 2 = 14/8 = 1 and 3/4 gal/hour. (1.75 gal/hour)

Answer:
415.7 mph or mph
Step-by-step explanation:
Did you make a sketch and got a right-angled triangle?
let the horizontal distance between the plane and the station be x miles
let the distance between the plane and the station be y miles
given: dx/dt = 480 mph
find: dy/dt when y = 6
y^2 = x^2 + 3^2
when y = 6
36 = x^2 + 9
x = √27
2y dy/dt = 2x dx/dt
dy/dt = (x/y)dx/dt
= √27(480)/6
= 415.7 mph or 416 mph
i think i hope this helps
