Questions & Step-by-Step Solutions
A car is moving at 80 km/h and a motorcycle is moving at 100 km/h in the same direction. What is the speed of the motorcycle relative to the car?
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, which is 20 km/h.
Relative Speed – Relative speed is the speed of one object as observed from another object, calculated by subtracting the speeds of the two objects when they are moving in the same direction.
