Questions & Step-by-Step Solutions

A boat can travel at a speed of 10 km/h in still water. If the speed of the current is 2 km/h, what is the speed of the boat downstream?
  • Step 1: Identify the speed of the boat in still water, which is 10 km/h.
  • Step 2: Identify the speed of the current, which is 2 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: 10 km/h (boat) + 2 km/h (current) = 12 km/h.
  • Step 5: The speed of the boat downstream is 12 km/h.
  • Relative Speed – Understanding how to calculate the effective speed of a boat when considering the influence of a current.
