Q
Q: Two cars start from the same point and travel in opposite directions. If car A travels at 40 km/h and car B at 60 km/h, how far apart will they be after 1 hour?
Solution: Relative speed = 40 + 60 = 100 km/h. Distance apart after 1 hour = 100 km.
Steps: 6
Step 1: Understand that two cars are starting from the same point and moving in opposite directions.
Step 2: Identify the speed of car A, which is 40 km/h.
Step 3: Identify the speed of car B, which is 60 km/h.
Step 4: Calculate the relative speed by adding the speeds of both cars: 40 km/h + 60 km/h = 100 km/h.
Step 5: Determine the time they have been traveling, which is 1 hour.
Step 6: Calculate the distance apart after 1 hour using the formula: Distance = Speed × Time. So, Distance = 100 km/h × 1 hour = 100 km.
