Answer:
Base 5
Step-by-step explanation:
We want to determine the base at which:
113 X 2 =231
We consider the last number of the result (231).
The base must be a number such that:
3 X 2 will have a remainder of 1.
3 X 2 = 6 = 5 Remainder 1
Therefore:
113 X 2 =231 in positive integral number base 5.
60 x 60 = 3600 (1 hour)
60 x 30 = 1800 (half hour)
3600 + 1800 = 5400 for one and half hour
answer C. 5400
