Time it took runner A to complete the marathon = 26.2 / 5.6 = 4 hrs 41 mins
Time it took runner B to complete the marathon = 26.2 / 6.4 = 4 hrs 6 mins
Time it took runner B to complete the marathon relative to when runner A started = 30 mins + 4 hrs 6 mins = 4 hrs 36 mins
Therefore, runner B will finnish ahead of runner A.
Let x be the time the two runners are at the same point, then
5.6x + 5.6(0.5) = 6.4x
6.4x - 5.6x = 2.8
0.8x = 2.8
x = 2.8/0.8 = 3.5
Therefore, runner B will catch up with runner A 3.5 hours after runner A starts the race.
<span>Runner B; Runner B will catch up to Runner A 3.5 hours after Runner A crosses the starting line.</span>
4 + (14 - 2) = 4 + 14 - 2
A. 4 - (-14 - 2) = 4 + 14 + 2 ------------------------WRONG
B. (4 - 14 ) - 2 = 4 - 14 - 2 --------------------------WRONG
C. 4 - (-14) - (2) = 4 + 14 - 2 ------------------------RIGHT
D. 4 + 14 + (-2) = 4 + 14 - 2 ------------------------RIGHT
E. - (-4 - 14) - 2 = 4 + 14 - 2 ------------------------RIGHT
Answer: C, D and E.

The fish is now 59 feet below sea level.
Answer:
5x + 2y = 3280
x+y = 785
x = 785 - y
5*(785 - y) + 2y = 3280
3925 - 5y + 2y = 3280
3925 - 3280 - 3y = 0
645 = 3y
y=645/3=215
x=785-215 = 570
Adults - 570 tickets, childs - 215 tickets.
570*5 + 215*2 = 3280
570 adult and 215 child and 3,280 in total
