26. KAYAKING Mai is kayaking on a river that has a current of 2 miles per hour. If r represents her rate in calm water, then r + 2 represents her rate with the current, and r - 2 represents her rate against the current. Mai kayaks 2 miles downstream and then d back to her starting point. Use the formula for time, t = − r , where d is the distance, to write a simplified expression for the total time it takes Mai to complete the trip.
