Question

City A and City B are 300 Km apart. You decide to drive the first half of the trip at 75 Km/hr and then decide to drive the second half of the trip at 100 Km/hr. What was the average velocity for the whole tri

Answer 1

Answer: 87.5 km/hr

Step-by-step explanation:

Since the speeds are split in halves and are each ridden for the same amount of time (150 km), we just have to find the mean (average) of both speeds.

To find the mean, we need to add the terms and divide the sum by the number of terms we put it. So our terms in the set are 75 and 100.

So 75+100=175 and
`(175)/(2)`=87.5 km/hr. They can also be written as 87 kilometers & 5 hectometers or 88 kilometers (rounded to the nearest kilometer).

Hope that helped a lot. Let me know any further questions.
