Questions & Step-by-Step Solutions
A car travels at 90 km/h and a truck at 60 km/h in opposite directions. What is the relative speed of the car with respect to the truck?
Correct Answer: 150 km/h
Step 1: Identify the speed of the car, which is 90 km/h.
Step 2: Identify the speed of the truck, which is 60 km/h.
Step 3: Since the car and truck are moving in opposite directions, we need to add their speeds together.
Step 4: Add the speed of the car (90 km/h) to the speed of the truck (60 km/h).
Step 5: Calculate 90 km/h + 60 km/h, which equals 150 km/h.
Step 6: The relative speed of the car with respect to the truck is 150 km/h.
Relative Speed – Relative speed is the speed of one object as observed from another object, calculated by adding their speeds when they are moving in opposite directions.
