Answer :
Final answer:
In mathematics, the domain of a function refers to the set of all possible input values. In this context, the domain of the function d(t) = 97.8t is 0 ≤ t ≤ 478, representing the total amount of hours Bertrand Piccard and Brian Jones traveled.
Explanation:
In the context of this problem, the domain of a function refers to the set of all possible input values (in this case, time in hours) that can yield an output. Since Bertrand Piccard and Brian Jones traveled for a total of 478 hours, the domain of the function d(t) = 97.8t is 0 ≤ t ≤ 478. This means the function is defined for all values of t between 0 and 478, inclusive. Any other value outside this range would not be relevant in this context, as it would indicate a time beyond, or before, their journey.

Answer:
Distance traveled= 41968.4 km
The domain of the function is t
t(h)= 478
h = hours
Step-by-step explanation:
the distance that they traveled in kilometers, d, can be modeled by
d(t) = 97.8t
where t is the time in hours
They traveled a total of 478 hours.
Distance traveled d(t)
d(t) = 87.8(478)
d(t) = 41968.4
Distance traveled= 41968.4 km
The domain of the function is t
t(h)= 478
