Answer:
6⅓ hours (or 6 hours and 20 minutes)
Explanation:
For Khalil on foot;
Let;
Speed = x miles/hour
Time = 4 hours
Distance = D (miles)
Speed = distance/time
x = D/4
D = 4x miles
For Khalil on the bus;
The bus travels at 6 times his walking rate, therefore;
Speed = 6x miles/hour
Bus follows a route that is twice as long, therefore;
Distance = 2D (miles)
Time = T (hours)
Speed = distance/time
6x = 2D/T
Remember, from above, D = 4x
Therefore,
6x = 2(4x)/T
6x × T = 8x
T = 8x/6x
T = 4/3 hours = 1⅓ hours
Therefore time spent by khalil on the bus = 1⅓ hours or 1 hour, 20 minutes.
Total hours spent on entire trip = hours khalil spent walking + lunch hour + hours khalil spent on the bus
Total hours = 4 + 1 + 1⅓ = 6⅓ hours
Answer:
For research, the observation method was used. The researchers took into account a variety of data: recording animal behavior on a camera, fecal samples that give an idea of nutrition, artifacts made by monkeys, complex transect (that is, on a special rectangular plot of land) studies, and so on.

Answer:
hypothesis
Explanation:
A hypothesis is a small and precise prediction about the study by the researchers. The prediction made by the researcher is testable. The explanation given relies on the facts which are known to the researcher but has not been proved through the research. The prediction of Dr. Colby about the sale of the hamburger is an example of a hypothesis.
