First covert the feet to meters.
1 meter = 3.3 feet.
Divide the total number of feet by 3.3 to get total number of meters:
198 / 3.3 = 60 meters per second.
Multiply meters per second by 15 seconds:
60 x 15 = 900 meters in 15 seconds.
Her credits need to be AT LEAST EQUAL TO OR GREATER THAN 144 (credit hours) so we can eliminate choices B and D.
She already completed 4 semesters in which she receives 15 credit per semester.
This expression can be written as 4(15).
She needs to do a certain remaining hours of credit which can be represented by c and only c without any other coefficient.
So, the most reasonable choice here is A.
