Questions & Step-by-Step Solutions

A boat goes downstream at a speed of 20 km/h and upstream at 10 km/h. What is the speed of the boat in still water? (2022)
  • Step 1: Identify the downstream speed of the boat, which is 20 km/h.
  • Step 2: Identify the upstream speed of the boat, which is 10 km/h.
  • Step 3: Add the downstream speed and the upstream speed together: 20 km/h + 10 km/h.
  • Step 4: Calculate the sum: 20 + 10 = 30 km/h.
  • Step 5: Divide the total by 2 to find the speed in still water: 30 km/h / 2.
  • Step 6: Calculate the final result: 30 / 2 = 15 km/h.
  • Relative Speed – Understanding how the speed of a boat changes when moving with or against the current.
  • Average Speed Calculation – Calculating the average speed using the speeds in different directions.
