A boat is currently 63 miles from its destination and is traveling against a river current. The boat travels 10 miles per hour (mph) in still water. The boat's distance from its destination is given by the following formula. D=63-h(10 - c) Given: D = distance in miles, h = number of hours, c = speed of the river's current in mph What is a correct formula for the boat's distance from its destination after 3 hours
