Answer:
Can you show the drop down choices?
Answer:
8
Step-by-step explanation:
0) the basic formula is: L=v*t, where L - distance, v - speed/velocity; t - time;
1) if the person's speed in still water is 'v' and the speed of water is 5 (according to the condition), then the upstream speed is 'v-5' and the downstream speed is 'v+5';
2) according to the condition the upstream time and the downstream time are the same, it means t₁=t₂=t, where t₁=upstream time and t₂=downstream time;
3) according to the items above it is possible to make up the equation of the upstream travel: t(v-5)=3; ⇒ t=3/(v-5);
4) according to the items above it is possible to make up the equation of the downstream travel: t(v+5)=13; ⇒ t=13/(v+5);
5) if t=3/(v-5) and t=13/(v+5), then

Answer:
20
Step-by-step explanation:
<em>5+5+5+5</em>
Total distance from w to z is -10 to 6 = 16
Add the ratios: 2 + 3 + 3 = 8
Divide distance by total ratio: 16/8 = 2
Multiply each ratio by 2 : 2x 2 = 4, 3 x 2 = 6, 3 x 2 = 6
WX is 4 units apart, add 4 to -10 to get x = -6
Answer: A. -6
