PLEASE HELP 9, 10, 11, 12 find the values of x and y that make the quadrilateral a parallelogram

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

it would have to be 3/0

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
