Questions & Step-by-Step Solutions
Two trains start from the same point and travel in opposite directions. Train A travels at 80 km/h and Train B at 100 km/h. How far apart will they be after 1 hour?
Step 1: Identify the speeds of both trains. Train A travels at 80 km/h and Train B travels at 100 km/h.
Step 2: Since the trains are moving in opposite directions, we need to add their speeds together.
Step 3: Calculate the total speed: 80 km/h + 100 km/h = 180 km/h.
Step 4: Determine the time they have been traveling, which is 1 hour.
Step 5: Use the formula for distance: Distance = Speed × Time.
Step 6: Plug in the total speed and time: Distance = 180 km/h × 1 hour.
Step 7: Calculate the distance: 180 km/h × 1 = 180 km.
Step 8: Conclude that after 1 hour, the two trains will be 180 km apart.
