Answer:
The second voyage lasted 480 days
Step-by-step explanation:
We are asked to calculate the number of days in which the second voyage lasted given the difference between the number of days the two voyages lasted.
To solve this problem, we first assign variables. Let the number of days the first voyage lasted be f while the number of days the second voyage lasted be s.
We know that the first voyage lasted 43 more days than the second voyage.
Mathematically, f = 43 + s....(I)
Also, the two voyages combined lasted 1003 days. Mathematically:
f + s = 1003........(ii)
We substitute i into ii
43 + s + s = 1003
43 +2s = 1003
2s = 1003 - 43
2s = 960
s = 960/2 = 480 days
