To find the distance between the points given in the figure of the problem above, you must apply the formula for calculate the distace between two points, which is shown below:
d=√[(x2-x1)^2+(y2-y1)^2]
When you substitute the values, you obtain:
d=√[(x2-x1)^2+(y2-y1)^2]
d=√[(-1-2)^2+(-5-5)^2]
d=10.4
The answer is:10.4
Antti entered a -kilometer race. His goal is to finish in one hour. He starts off sprinting, and completes the first kilometers of the race at an average speed of kilometers per hour.
To achieve his goal of a one-hour finish time, what average speed (in kilometers per hour) must Antti maintain for the last kilometers of the race?
Enter your answer as a number in decimal form, without units.Hint(s):
