Answer:
The hiker has to climb 941.26 to ''work off'' the calories.
Explanation:
Let's first find out how much energy the hiker gets from 150 food calories.
This is:
Energy = 150 * 4186
Energy = 627.9 kJ
To burn all of this off, we set it equal to the gravitational potential energy, and then solve for the height.
This is:
Gravitational Potential Energy (G.P.E) = 629700
G.P.E = mass * gravity * height
Thus,
mass * gravity * height = 629700
68 * 9.81 * height = 629700
height = 941.26 meters
As 1 km = 1000 m = 1000,00 cm,
So, 1 cm = (1/1000,00) km
1 hour = 60 × 60 s = 3600 s
So, 1 s = (1 / 3600) hour
The light travels at a speed of 
.
In kilometer/hour,
