Answer:
2.5 miles per hour
Step-by-step explanation:
ok, so we already know how long she walked in 1/2 hour and we need to find out how many miles in one full hour. So, i multiplied 1 1/4 times two to make up the one full hour and I got 2.5 miles. So the rate is 2.5 mph.
 
        
             
        
        
        
if x= 7 what is the value of x-4
7 - 4
=3
if y=3 what is the value of 8y
8 x 3
= 24
if x=7 what is the value of 3x-4
(3 x 7) - 4
= 17
if x=7 and y=3 what is the value of 2x-7y
(2 x 7) -(7 x 3)
= - 7
if x=7 and y=3 what is the value of 4y-X
(4 x 7) - 3
= 25
Hope this helps
