Jenny drove 335 miles in 5 hours at the same rate how long would it take her to drive 871 miles?

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.

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
