Use the distribution property.
Answer:
3, 8, 14, 30, 58
Step-by-step explanation:
As with all formulas, put the numbers in place of the corresponding variables, and do the arithmetic.

The first 5 terms of the sequence are 3, 8, 14, 30, 58.
Since the question is asking for the time units to be in hours, you want to convert 30 minutes to an hour; 0.5
We’re able to use the basic motion formula for velocity to work out this question.
Velocity = distance / time
Velocity = 5 / 0.5
Velocity = 10km/h
Therefore, Stanley’s average speed was 10 kilometres per hour. :)
I believe the correct answer to your question would be choice B. The trail is no more than 6 miles long.
