a boat goes 30km upstream and 44 downstream in 10 hours.
3. When the boat goes downstream, it gets a boost from the current, so its effective speed is (x+10) km/h. Step 4/13 4. We can use the formula distance = speed x time to set up two equations: - 30 = (x-10) t1 (where t1 is the time taken to go upstream) - 44 = (x+10) t2 (where t2 is the time taken to go downstream) Step 5/13 5.
