An odometer in a car has a reading of 50 km at the beginning of a trip and a reading of 125 km half an hour later. What is the average speed of the car?
A. 3.75 km/h
B. 62.5 km/h
C. 1250 km/h
D. 250 km/h
I say it's D.
I think you are guessing, trying to answer mooch. I will be happy to critique your work. You might be surprised on this one.
Total distance traveled divided by the total time taken.
To find the average speed of the car, we need to divide the total distance traveled by the total time taken.
In this case, the initial reading of the odometer was 50 km, and after half an hour, the reading was 125 km. Therefore, the total distance traveled during this trip is 125 - 50 = 75 km.
We are given that the trip took half an hour. To convert this into hours, we divide by 60 since there are 60 minutes in an hour. So, the total time taken in hours is 30 minutes ÷ 60 = 0.5 hours.
Now, we can calculate the average speed by dividing the total distance (75 km) by the total time (0.5 hours).
Average speed = Total distance ÷ Total time = 75 km ÷ 0.5 hours = 150 km/h
Therefore, the correct answer is not D (250 km/h). It is not one of the given options, but the correct answer is 150 km/h.
