A car is moving at 80 km/h and a motorcycle is moving at 100 km/h in the same direction. What is the relative speed of the motorcycle with respect to the car?
20 km/h
180 km/h
100 km/h
80 km/h
Relative speed = Speed of motorcycle - Speed of car = 100 km/h - 80 km/h = 20 km/h.

Q
Q: A car is moving at 80 km/h and a motorcycle is moving at 100 km/h in the same direction. What is the relative speed of the motorcycle with respect to the car?
Solution: Relative speed = Speed of motorcycle - Speed of car = 100 km/h - 80 km/h = 20 km/h.
Steps: 6
Step 1: Identify the speed of the motorcycle, which is 100 km/h.
Step 2: Identify the speed of the car, which is 80 km/h.
Step 3: Since both the motorcycle and the car are moving in the same direction, we need to find the difference in their speeds.
Step 4: Subtract the speed of the car from the speed of the motorcycle: 100 km/h - 80 km/h.
Step 5: Calculate the result of the subtraction, which is 20 km/h.
Step 6: The relative speed of the motorcycle with respect to the car is 20 km/h.
