A motorboat maintained a constant speed of 28 miles per hour relative to the water in going 45 miles upstream and then returning. The total time for the trip was 3.5 hours. Use this information to find the speed of the current.
The speed of the current is 7 miles per hour. Step-by-step explanation: Let × represent speed of the current. We have been given that a motorboat maintained a constant speed of 11 miles per hour relative to the water in going 18 miles upstream and then returning. The speed of motorboat while going upstream would be 11 The speed of motorboat while going downstream would be 11 + 2 Time Distance Speed
