Question: A car is moving at 80 km/h and a motorcycle at 60 km/h in the same direction. What is the relative speed of the motorcycle with respect to the car?

Options:

20 km/h
60 km/h
80 km/h
140 km/h

Correct Answer: 20 km/h

Solution:

Relative speed = Speed of motorcycle - Speed of car = 60 km/h - 80 km/h = -20 km/h (20 km/h behind).

Questions & Step-by-Step Solutions

A car is moving at 80 km/h and a motorcycle at 60 km/h in the same direction. What is the relative speed of the motorcycle with respect to the car?

Step 1: Identify the speed of the car, which is 80 km/h.
Step 2: Identify the speed of the motorcycle, which is 60 km/h.
Step 3: Since both vehicles are moving in the same direction, we need to find the relative speed by subtracting the speed of the car from the speed of the motorcycle.
Step 4: Perform the subtraction: 60 km/h (motorcycle) - 80 km/h (car) = -20 km/h.
Step 5: The negative sign indicates that the motorcycle is behind the car, so we can say the relative speed is 20 km/h behind.

Relative Speed – Relative speed is the speed of one object as observed from another object, calculated by subtracting their speeds when moving in the same direction.
