Answer:
Step-by-step explanation:
solution is (4,3)
OR
x=4
y=3
this point lies in both the tables.
we have to find a pair which lies on both.
Yes. I believe so. If u solve the equations you get x=1/2 and y=-1
Let V, be the rate in still water and let C = rate river current
If the boat is going :
upstream, its rate is V-C and if going
downstream, its rate is V+C,
But V = 5C, then
Upstream Rate: 5C - C = 4 C
Downstream rate: 5C+C = 6C
Time = distance/Rate, (or time = distance/speed) , then:
Upstream time 12/4C and
Downstream time: 12/.6C
Upstream time +downstream time:= 2h30 ' then:
12/4C + 12/.6C = 2.5 hours
3/C + 2/C = 5/2 (2.5 h = 5/2)
Reduce to same denominator :
5C = 10 and Rate of the current = 2 mi/h
Answer:
3 1/6
Step-by-step explanation:
2 1/2 + 2/3 = 2 3/6 + 4/6. add 3 and 4, you get 2 7/6. simplify by taking 6 from 7 and add 1 to 2. that leaves you with the answer
