Q: Two cars start from the same point and travel in opposite directions at speeds of 70 km/h and 50 km/h. How far apart will they be after 2 hours?

Solution: Relative speed = 70 + 50 = 120 km/h. Distance apart after 2 hours = 120 × 2 = 240 km.

Steps: 8

Step 1: Identify the speeds of the two cars. Car A travels at 70 km/h and Car B travels at 50 km/h.
Step 2: Since the cars are moving in opposite directions, we need to add their speeds together to find the relative speed.
Step 3: Calculate the relative speed: 70 km/h + 50 km/h = 120 km/h.
Step 4: Determine how long the cars have been traveling. In this case, they have been traveling for 2 hours.
Step 5: Calculate the distance apart after 2 hours using the formula: Distance = Speed × Time.
Step 6: Substitute the values into the formula: Distance = 120 km/h × 2 hours.
Step 7: Perform the multiplication: 120 × 2 = 240 km.
Step 8: Conclude that after 2 hours, the two cars will be 240 km apart.
