6. find the area of the polygon pqrs with its vertices at p(1,-1), q(6, -1), r(6,-6), and s(1, -6).
a. 50 square units
b. 12.5 square units
c. 20 square units
d.25 square units

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.

3 qrs + 3/2 xy hope this : /
