Answer:
Explanation:
As we know that 1 lb fat can be used to expend 4.1 k Calorie of energy
so here we know that we have to use 7.56 lb of body fat
so here the total energy that is to be utilized is given as
so we will have
now we know that runner expends the energy at rate of 1850 kJ/h
so we have
so it is
now we know that time to burn this energy is given as
Answer:
The solution is given below:
Explanation:
The computation of the speed is shown below
As we know that
Speed = distance ÷ time
where
distance is 2000 km
And, the time is 2.5 hours
SO, the speed is
= 2,000 ÷ 2.5
= 800 km/h
Now the distance would be the same i.e. 2,000 km
but the time is 2 hours
So, the speed is
= 2,000 km ÷ 2 hours
= 1,000 km/hr
The direction should be opposite to the first airplane
