Please provide answer choices. As I have nothing to look off of, I cannot answer accurately. However, I can provide a definition to the word, "slope".
Explanation:
The equation for slope can most often be written out as y=mx+b, where m is the slope, and b is the intercept. The slope of a line is the number that shows the rise and run of the line.
sorry i don't really have an explanation I just looked at the picture and i guess imagined it in my head? lol sorry but here are the answers I hope that helps at least a little bit :))
You first need to know how much miles it takes on the trail. Then you look 20 x 3 is one hour. And if the 3 group said it takes 2 hours waking for them its like this, the first group takes one hour to go thru the trail, but the second group takes and hour and half the 3 group takes 2 hours.
