A.
The rate is 12:2
B.
Set up a proportion:
12/2 = x/5
Multiply 5 to both sides:
60/2 = x
Divide:
30 = x
So he will walk 30 miles in 5 hours.
C.
To find out, we can divide 12 / 2.
12 / 2 = 6 miles per hour
3miles/ 28 minutes times 42 minutes is equal to 4.5 miles.
Therefore, Eric run 4.5 miles in 42 minutes.
Hopefully this helps!
The answer is 8 2/4.
