Margaret traveled 80 miles to the appointment.
Step-by-step explanation:
Given,
Speed while driving for appointment = 80 mph
Speed while coming back = 70 mph
Let,
x be the time taken for the trip
y be the distance covered
Distance = Speed*Time
y = 80x Eqn 1
Time taken in return trip = x+1/7
y = 70(x+1/7)
Eqn 2
Putting value of y from Eqn 1 in Eqn 2
Dividing both sides by 10
x = 1 hour
Putting x = 1 in Eqn 1
Margaret traveled 80 miles to the appointment.

Answer:
The value of y is 14.
Step-by-step explanation:
Given,
Length of AB =
Length of BC =
Length of CD =
Since ABCD is an isosceles trapezoid then according to property of trapezoid which is given below;
"In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length."
So Length of AB = Length of CD
Hence the value of y is 14.
