Answer:
Okay, I think the easiest way to approach this problem is to first convert the mixed fractions to irregular fractions:
8
1
8
=
8
⋅
8
+
1
8
=
65
8
7
2
5
=
7
⋅
5
+
2
5
=
37
5
We want the total number of miles, so our equation is:
distance=
65
8
+
37
5
The LCD of 5 and 8 is 5*8=40, so:
distance=
325
40
+
296
40
distance=
621
40
=
15
21
40
miles.
Hope this helps!
