Question

Use a system of equations to solve a problem involving distance, speed, and time.

Answer 1

Answer:

Speed of boat in still water is 26km/hr

Step-by-step explanation:

Let the speed of boat in still water be x and speed of stream by y.

Speed at which it went upstream would be (x-y) and the speed at which it went downstream would be (x+y). According to question x+y=24 and x-y=28. x=26 and y=-2.
