Why the speed of the boat is still in the water? Math problems But?
3kph is the downstream speed. The river upstream of the boat Such as the time it takes to travel 35km to 25km journey. Why is the speed of the boat What is still in the water?
18 km / h Aroha, but I can explain it Let me tell you. Let's analyze the situation. Tell the upstream speed of RUP, If Rdown downstream speed is the speed of water R and the time is still Ing spaces, travel do's, let's translate the question. "Boat Travel 25km upstream at the time it takes to travel the same Downstream, 35km. "This is a Rdown * t * t = RUP = 25 and 35 because the speed of the stream Because of 3, then we say that we know Rdown = R - R + 3 = 3, and the RUP. Therefore, we can see that (R - 3) * t = 25 (R + 3) * t = 35 Therefore, we have two simple equations, 2 prints. This solution is different, but this It will do. Rearranging, we're a - 3t = 25, so Earned = 25 + 3t see. In addition, earned + 3t = 35, it earned = 35 - 3t Therefore, 25 + 3t = 35 - 3t, 6t = 10 really, really do not = 5 / 3. This study = (25 As + 3 * (5 / 3)) / (5 / 3) = (25 + 5) * 3 / 5 = 18.
