Hello!
Since we know how much they walked in 4/9 of an hour, we will divide 4/5 by 4/9 to get 4/9 to one.

÷

=

They went 1 4/5 mph or
1.8 mph.
I hope this helps!
Answer: 1/4
Step-by-step explanation:
2x + 3(8 - 3x) = 3
2x + 24 -9x = 3
-7x = -21
x = 3
y = 8 - 3x
y = 8 - 3(3)
y = 8-9
y = -1
Check the math:
2(3) + 3(-1) = 6 - 3 = 3
Change into improper fraction
take 3 x 25+18 divided by 25=93\25
93\25=3.72
