Questions & Step-by-Step Solutions
If a train leaves a station heading north at 60 km/h and another train leaves the same station heading south at 80 km/h, how far apart will they be after 2 hours?
Correct Answer: 280 km
Step 1: Identify the speed of the first train, which is 60 km/h.
Step 2: Identify the speed of the second train, which is 80 km/h.
Step 3: Determine the time the trains are traveling, which is 2 hours.
Step 4: Calculate the distance traveled by the first train in 2 hours: 60 km/h * 2 hours = 120 km.
Step 5: Calculate the distance traveled by the second train in 2 hours: 80 km/h * 2 hours = 160 km.
Step 6: Add the distances of both trains to find out how far apart they are: 120 km + 160 km = 280 km.
Relative Motion – Understanding how two objects moving in opposite directions can be analyzed to find the total distance between them.
Speed and Distance Calculation – Applying the formula distance = speed × time to calculate how far each train travels.
