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
![4t=6(3-t)](https://tex.z-dn.net/?f=4t%3D6%283-t%29)
![4t=18-6t](https://tex.z-dn.net/?f=4t%3D18-6t)
![10t=18](https://tex.z-dn.net/?f=10t%3D18)
t=1.8
Hence, time taken to uphill = 1.8 hours
Time taken to down hill = 3-18 = 1.2 hours

Step-by-step explanation:
An apothem is a perpendicular drawn from the centre of the triangle to one of its sides.
The three apothems OD, OE, and OF divide ∆ABC into six smaller congruent triangles.
1. Area of ∆OCD
CotOCD = OD/OC
cot30 = CD/6
√3 = CD/6
CD = 6√3
A= ½bh
A = ½ × 6√3 × 6 = 18√3 in²
2. Area of ∆ABC
A = 6 × area of ∆OCD = 6 × 18√3 = 108√3 in²

A mile is a unit of length most commonly equivalent to 5280 feet (1760 yards, or about 1609 metres).
