Joe runs one lap around a track in 80 seconds. Joe and Jim meet after 30 seconds.We know how long does it take for Joe to run one lap, so we can calculate what distance he runs in 30 seconds:
He runs half lap for 40 seconds. He runs quarter lap for 20 minutes and he runs 1/8 lap for ten minutes. So for 30 seconds he runs 3 * 1/8 lap=3/8 lap.
Because Jim runs in opposite direction this means that he will meat with Joe at 1-3/8=5/8 lap. So, Jim runs 5/8 lap for 30 seconds.
1/8 lap Jim runs for 30/5=6 seconds, so Jim needs 8*6=48 seconds to run the lap.
After 30 seconds Joe has run e runs
120 seconds
1 min = 60 seconds
Answer: The required equation is 
Maria can cut 6 sections from the remaining rope.
Step-by-step explanation:
The total length of rope = 7 feet
since 1 feet = 12 inches
Therefore, 7 feet=
Let x be the number of sections.
Since the instructions are to use 34.5 inches of rope to tie a tarp on top the the tent. Then, the remaining rope should be cut 8 1/4 inch sections to tie tent to stakes in the ground.
then the required equation will be

So, maria can cut 6 sections.
Answer:
Option A.
Step-by-step explanation:
It is given that the smallest of 6 consecutive integers is p. So, all numbers are
The greatest is q.
Now, the value of the average of p and q in terms of p is
Therefore, the correct option is A.
A and B
Both A and B, when simplified get -(1/6), because the others have either 0 or 2 negative signs, denoting a positive end result.
