Let the time to hike up the hill = t
As given that the total time time up and down is 3 hrs, therefore
The time down the hill = 3-t
The distance up and down is the same.
Distance = speed * time
t=1.8
Hence, time taken to uphill = 1.8 hours
Time taken to down hill = 3-18 = 1.2 hours
Answer:
Distance between two cities is 193.94 miles.
Step-by-step explanation:
We have,
Madison and Wisconsin have latitudes 43.0731°N and 45.9172°N respectively.
Thus, their difference is 45.9172°N - 43.0731°N = 2.8441°
We assumed, the diameter of earth is 7917.5 miles.
So, the radius = = 3958.75 miles
So, using the cosine formula, we have,
i.e.
i.e.
i.e.
i.e. a= 193.94 miles.
Hence, the distance between two cities is 193.94 miles.
