Answer:
The avarage power of the body is 96.898 watts.
Explanation:
We must notice that given definition of power implies a constant consumption of energy, so that we should assume that energy consumption is constant. A Calorie is equal to 4186 joules. If we know that and
, the power of body, measured in watts, is:
The avarage power of the body is 96.898 watts.
Answer:
Explanation:
Total =40 miles.
y miles at x miles/hr.
40- y miles at 1.25 x miles/hr.\
We know that
Distance = time x velocity
For y miles
Lets time taken to cover y miles is t
y = x t
t=y/x -----------1
For 40- y
Lets time taken to cover 40- y is t'
40- y = 1.25 x t'
t'=(40-y)/1.25x -----------2
By adding both equation
t+t'=y/x + (40-y)/1.25x
t+t'=(32+0.2y)/x
Now lets time T taken by Marla if she will travel at x miles per hr for entire trip.
40 = x T
T=40/x
So
To find numerical value of above expression we have to know the value of y.
