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.
Answer:
Step-by-step explanation:
the black dot on -3 represents less than equal to X and the white dot on 2 represents X is less than 2
Answer:
Step-by-step explanation:
So since each question is 5% (100/20=5)
we can do ((13*5)/2) because of half credit we divide by two
now we get 32.5% back
32.5%+35%=67.5%
unless of course of extra points on other assignments, the highest grade you can get in that class (if every other thing is a 100%) is an 87 if im not mistaken.
The answers is : d
Because 11.5 plus 3.5 would equal 15 and then the approximate length would end up being 14
