#1: 4*5 + 4*6=20+24=44
#2: 4*(5+6)=4*11=44
The length of the trail is 98.5 KM, all you need to do is divide the total distance by the number of times she went on it.
The answer is 3) 5+r/14
Let's go segment by segment:
<span>"five plus" means addition, so we have 5 +
</span><span>"the quotient of r and 14" is the division result, so sign / must be present: 14/r
</span>
Therefore "five plus the quotient of r and 14" is 5 + 14/r
