Let the time that you caught up with your friend be t, then
8.5 - 3.4t = 8 - 3t
3.4t - 3t = 8.5 - 8
0.4t = 0.5
t = 0.5/0.4 = 1.25
therefore, you will catch up with your friend after 1.25 hours.
b.) time it will take you to cross the finnish line = 8.5/3.4 = 2.5 hours
After 2.5 hours, distance covered by your friend = 3 x 2.5 = 7.5 miles
Therefore, when you cross the finish line, you are 8 - 7.5 = 0.5 miles ahead of your friend.

<u>Step-by-step explanation:</u>
The "point" on the inequality symbol points to the smaller number
- < is the "less than" inequality symbol
- > is the "greater than" inequality symbol
- = is the "equal" symbol
18) 3 = 3
20) 
22) 0.8 = 4/5 Note: 4÷5 is 0.8
26) 0.075 < 0.39
28) -5.2 < -4.8
30) 0.4 > 
32) 
To find the median you have to put all the numbers in order from smallest to largest and find the one that's in the middle.
All of the numbers listed are already in order, and the one that lies in the middle is 40. So the answer is 40.
