While Steve and LeRoy were fishing 1 mile from shore, their boat springs a leak and water comes in a constant rate of 10 gallons per minute.
The boat will sink if it takes in more than 30 gallons of water. Steve starts rowing towards the shore at a constnat rate of 4 miles per hour while LeRoy bails water out of the boat.
What is the slowest rate in gallons per minute, at which LeRoy can bail water out of the boat if they are to reach the shore without sinking?
Please show all work.
