Answer:
Answer is third option no.4
Answer: 1. 2nd endpoint (24,-18) 2. 2nd endpoint: (-19,4)
Step-by-step explanation:
1. 
= 7 x = 24
= -6 y= -18
2nd endpoint: (24,-18)
2. 
= -10 x= -19
= 2 y= 4
D=vt
So they will travel downstream and upstream the same distance. Downstream they will travel:
d=(2+18)t1
Upstream they will travel:
u=(18-2)t2
Since d=u we can say:
20t1=16t2
We are told the trip lasts 3 hours so t1+t2=3, t2=3-t1, using this in the equation above we have:
20t1=16(3-t1)
20t1=48-16t1
36t1=48
t1=4/3 hours, and from earlier we saw that d=20t1 so:
d=20*4/3
d=80/3 miles
d=26 2/3 miles.
