Answer:
D
Step-by-step explanation:
r = boat's rate
c = current's rate
1. A boat traveled in a river upstream for a distance of 30 miles. Travelling upstream, the current obstructs the movement, so the actual boat's rate is r - c mph.
If the boat took 4 hours to travel upstream, then
2. A boat traveled in a river downstream for a distance of 30 miles. Travelling downstream, the current helps the movement, so the actual boat's rate is r + c mph.
If the boat took 3 hours to travel downstream, then
So, we get the system
4r-4c=30
3r+3c=30
Answer:
The correct answer is y/2
Step-by-step explanation:
It is given that,
(x + 3)/ 3 = (y + 2)/ 2
<u>To find x/3</u>
(x + 3)/ 3 = (y + 2)/ 2
⇒ x/3 + 3/3 = (y + 2)/2
x/3 + 1 = (y + 2)/2
x/3 = (y + 2)/2 - 1
x/3 = (y + 2)/2 -2/2
x/3 = (y + 2 - 2)/2
x/3 = y/2
Therefore the correct answer is x/3 = y/2
