Robert uses a wheelbarrow to haul wood from his backyard to the back of the neighbor's house, located 80 m away. If he takes 3 breaks evenly when pushing the wheelbarrow the complete distance, at what distance does he take his first break.

26.66 meters

Step-by-step explanation:

The final destination of his neighbor's house is 80 meters away so we can assume that the starting point of Robert's backyard is point 0 meters. Since he takes 3 breaks evenly dispersed between the entire trip, then we simply divide the total distance by 3 in order to distance between each break.

80 / 3 = 26.66 m

Therefore, the distance between each breakpoint is 26.66 meters which also means that the first break is taken at a distance of 26.66 meters. This is because since it is the first break it is added to the starting point of 0 like so...

0 + 26.66 = 26.66 meters

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
