Answer:

The answer is Ari, Beth, Cindy

Explanation

Ari

2¾ miles is 2.75 miles
speed of 2½ miles per hour is 2.5 mi/h

DISTANCE = SPEED × TIME

t = d/s

= 2.75/2.5

= 1.1hr

= 66mins

Beth

1¾ miles is 1.75 miles
speed of 1¼ miles per hour is 1.25 mi/h

t = d/s

= 1.75/1.25

=1.4hr

=84mins

Cindy

1hr 21mins is 81mins

What is the solution set of (x^2+x-6/x-7)<_0

Vlada [557]

X^2 + x - 6
------------- <= 0
x - 7

(x + 3)(x - 2)
---------------- <= 0
x - 7

2 critical values are x = -3 and x = 2

if x <= -3 the the function <= 0 so that's one part of the solution
also x >= 2
x must be < 7 if its = 7 then the function is indeterminate. and values between 2 and 7 will give negative valu to function

The answer is choice A.
