Questions & Step-by-Step Solutions

In a race, A runs at a speed of 10 km/h and B runs at a speed of 15 km/h. If they start together, how much faster is B than A? (2022)
  • Step 1: Identify the speed of runner A, which is 10 km/h.
  • Step 2: Identify the speed of runner B, which is 15 km/h.
  • Step 3: To find out how much faster B is than A, subtract A's speed from B's speed.
  • Step 4: Perform the subtraction: 15 km/h (B's speed) - 10 km/h (A's speed).
  • Step 5: Calculate the result, which is 5 km/h.
