Q
Q: A boat can go 15 km/h in still water. If the speed of the current is 3 km/h, what is the speed of the boat downstream?
Solution:
Speed downstream = Speed of boat + Speed of current = 15 + 3 = 18 km/h.
Steps: 5
Show Steps
Step 1: Identify the speed of the boat in still water, which is 15 km/h.
Step 2: Identify the speed of the current, which is 3 km/h.
Step 3: To find the speed of the boat downstream, add the speed of the boat and the speed of the current together.
Step 4: Calculate the total speed: 15 km/h (boat) + 3 km/h (current) = 18 km/h.
Step 5: The speed of the boat downstream is 18 km/h.
