A) x * y = 48
B) x -y = 8
A) x = 48/y then substituting this into B)
B) 48/y -y = 8
B) 48 -y^2 = 8y
B) y^2 + 8y - 48 =0
x = 4 y = 12
12*4 = 48
12 -4 = 8
Formula d = vt
1 3/4= 1.75
1/4=0.25
So now plug into equation
To find v first to find per hr.
v = (1.75 miles) / (0.25 hrs) =
7 miles per hr
Distance per hr
d = (7 miles/hr)(1 hr) = 7 miles
In 3 hrs ?
d = (7 miles/hr)(3hr) = 21 miles
