The speed to the island is x. The speed to return is x+5.

The distance is the same so, 2.5 multiplied by x = 2×(x+5).

It took 2.5 hrs to get there and 2 hrs to return. Now all we have to do is solve.

 2.5*x = 2x + 10

 .5x = 10
x=20

 Therefore, the distance between islands is 2.5 × 20 = 50 miles.

hope this helps!

Llana [10]
For the answer tot he question above, let the number of t-shirts are represented by 't'
number of sweaters are represented by 's'

cost of 1t=10 and cost of 1s=20 so
10t+20s=2000 or (factor out the 10 if you want to simplify)
10(t+2s)=10(200)
divide both sides by 2
t+2s=200

Answer:

C) x=2 y=-1 z=3

Step-by-step explanation:

2x + y - z = 0

2(2) + (-1) - (3) = 0

0 = 0

x - y + z =6

2 - (-1) + 3 = 6

6 = 6

x + 2y + z = 3

2 + 2(-1) + 3 = 3

3 = 3
