Answer:

C) y =  4 - x

Step-by-step explanation:

Boat speed = 6m/h

River speed = 2m/h

Speed of the boat in upstream = 6m - 2m = 4miles per hour.

Rate of speed decrease = 1m/h

Here x represents the number of hours.

So the speed of the boat (y) = 4 - 1x

y = 4-x

Hope this will helpful.

Thank you.
