Answer:
B
Step-by-step explanation:
Multiply through by x+5
2(x + 1) = x + 5 - 1 Combine like terms
2x + 2 = x + 4 Subtract 2 from both sides.
2x = x + 4 - 2
2x = x + 2 Subtract x from both sides.
2x - x = 2 Combine
x = 2

4500 meters. You find this by adding 1/3 and 2/5 which equals 11/15. This means that the remaining 4/15 is 1200 meters long. Divide 1200 by 4 in order to find the distance per 1/15 and you get 300. Multiply 300 with 15 to get the total distance of the race.
