Question: A car travels 100 km in 2 hours and then 50 km in 1 hour. What is the total average speed of the car? (2019)

Options:

Correct Answer: 60 km/h

Exam Year: 2019

Solution:

Total distance = 100 + 50 = 150 km. Total time = 2 + 1 = 3 hours. Average speed = Total distance / Total time = 150/3 = 50 km/h.

A car travels 100 km in 2 hours and then 50 km in 1 hour. What is the total average speed of the car? (2019)

Correct Answer: 50 km/h

Step 1: Find the total distance traveled by the car. Add the two distances: 100 km + 50 km.
Step 2: Calculate the total distance: 100 + 50 = 150 km.
Step 3: Find the total time taken for the journey. Add the two times: 2 hours + 1 hour.
Step 4: Calculate the total time: 2 + 1 = 3 hours.
Step 5: Calculate the average speed using the formula: Average speed = Total distance / Total time.
Step 6: Substitute the values: Average speed = 150 km / 3 hours.
Step 7: Calculate the average speed: 150 / 3 = 50 km/h.

Average Speed – Average speed is calculated by dividing the total distance traveled by the total time taken.
Distance and Time Calculation – Understanding how to sum distances and times correctly is essential for calculating average speed.
