It took him 2.6 hours to reach the top
Data;
- Uphill = 6km
- Downhill = 4km
- Total time taken = 8 hours
<h3>Speed</h3>
Let us calculate the speed during uphill and downhill
Since the time it took them to descend is twice the time it took them to ascend,
- Let x represent the time taken to ascend

From the calculation above, it took him 2.6 hours to reach the top.

Answer:
I would say that it is none of the above that one is much more reasonable than the other ones
Step-by-step explanation:
Step-by-step explanation:

Decimals from 7.0 to 8.4 with an interval of 0.2 between each pair of decimals
We start with 7.0 and keep adding 0.2 till we get 8.4
7.0 + 0.2 = 7.2
7.2 + 0.2 = 7.4
7.4 + 0.2 = 7.6
7.6 + 0.2 = 7.8
7.8 + 0.2 = 8.0
8.0 + 0.2 = 8.2
8.2 + 0.2 = 8.4
So, the decimals from 7.0 to 8.4 with an interval of 0.2 are
7.2, 7.4, 7.6, 7.8, 8.0, 8.2

Probability Definition in Math-
- Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
- Four perspectives on probability are commonly used: Classical, Empirical, Subjective, and Axiomatic.
- For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .
- It’s simple. there are 7 digits, so that would mean you start with 0,000,000 and end with 9,999,999.
- If the highest digit is 9,999,999 and you add a 1 more to it, you have a total of 10M combinations.
