Answer:
1.3889 x 10¹¹ miles.
Explanation:
2 Years = 2 x 365 days = 730 days
2 years and 9 days = 739 days .
739 days = 739 x 24 = 17736 hours
2 years 9 days and 4.5 hours = 17736 + 4.5 = 17740.5 hours
17740.5 hours = 17740.5 x 60 x 60 = 63.865 x 10⁶ s
Distance travelled = velocity x time
2174.799173 x 63.865 x 10⁶ = 1.3889 x 10¹¹ miles.
Like a said the answer should be D XD

Answer:
The distance traveled by the skier is 5.309 km
Solution:
As per the question:
Mass of the skier, m = 64 kg
Coefficient of friction between the ski and the snow, 
Mass of snow, M = 5.0 kg
Now,
To calculate the distance, 's' traveled by the skier, in order to melt 5.0 kg of snow:
We know that:

where
= coefficient of friction
N = Normal Reaction
N = mg
Thus
(1)
Also,
(2)
where
= Latent Heat of fusion
Thus from eqn (1) and (2):


s = 5.309 km
