Questions & Step-by-Step Solutions
Two trains start from the same point and travel in opposite directions. If one train travels at 80 km/h and the other at 100 km/h, how far apart will they be after 2 hours?
Step 1: Identify the speeds of the two trains. Train 1 travels at 80 km/h and Train 2 travels at 100 km/h.
Step 2: Add the speeds of both trains together to find the total speed. 80 km/h + 100 km/h = 180 km/h.
Step 3: Determine the time they are traveling. In this case, they are traveling for 2 hours.
Step 4: Calculate the total distance apart after 2 hours using the formula: Distance = Total Speed * Time.
Step 5: Substitute the values into the formula: Distance = 180 km/h * 2 h.
Step 6: Perform the multiplication: 180 km/h * 2 h = 360 km.
Step 7: Conclude that after 2 hours, the two trains will be 360 km apart.
