Answer:
y = 1
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y =  ← k is the constant of variation
 ← k is the constant of variation
To find k use the condition y = 25 when x =  , then
 , then
25 =  = 5k ( divide both sides by 5 )
 = 5k ( divide both sides by 5 )
5 = k
y =  ← equation of variation
 ← equation of variation
When x = 5, then
y =  = 1
 = 1

Given that Noah and his grandfather were returning home from a walk, and when they were 800 m away from the house, the grandfather said that he was thirsty, so Noah immediately ran home, got a bottle of water, and ran back to meet his grandfather who never stopped walking at a steady pace, to determine how many meters from the house did they meet if noah ran four times as fast as his grandfather walked, the following calculation must be made:
- 200 x 4 = 800 - 200 = 600
- 300 x 4 = 1200 - 800 - (800 - 300) = 100
- 325 x 4 = 1300 - 800 - (800 - 325) = -25
- 320 x 4 = 1280 - 800 - (800 - 320) = 480 - 480 = 0
Therefore, they met 480 meters from the house.
