A train travels 67 km, north along a straight track in 39 minutes. What is the train's average velocity in kilometers per minutes?
A. 28Km/mins
B. 1.72Km/mins
C. 0.582Km/mins
D. 106 Km/mins

B. 1.72Km/mins

Explanation:

The topic is Mathematics, not Biology but okay!

All you have to do is 67/39 which equals 1.72km/mins.

This is because you have to work out the average speed in kilometres per minute. 39/39 = 1 minute

I hope this helps you!! ^-^

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
