Q: If a car travels at a speed of 80 km/h and a bike travels at 60 km/h, how far apart will they be after 1 hour if they start from the same point and travel in the same direction?
Solution: Relative speed = 80 - 60 = 20 km/h. Distance apart after 1 hour = 20 km.
Steps: 6
Step 1: Identify the speed of the car, which is 80 km/h.
Step 2: Identify the speed of the bike, which is 60 km/h.
Step 3: Determine the relative speed by subtracting the bike's speed from the car's speed: 80 km/h - 60 km/h.
Step 4: Calculate the relative speed, which is 20 km/h.
Step 5: Since they travel for 1 hour, the distance apart after 1 hour is equal to the relative speed.
Step 6: Therefore, the distance apart after 1 hour is 20 km.
