Questions & Step-by-Step Solutions
A boat can travel at a speed of 10 km/h in still water. If it goes downstream, its speed increases by 2 km/h. What is its speed downstream? (2021)
Step 1: Identify the speed of the boat in still water, which is 10 km/h.
Step 2: Determine the increase in speed when going downstream, which is 2 km/h.
Step 3: Add the speed in still water (10 km/h) to the speed increase (2 km/h).
Step 4: Calculate the total speed downstream: 10 km/h + 2 km/h = 12 km/h.
