Answer:
C. ks/(60c)
Step-by-step explanation:
Units analysis is helpful here.
A. (60 sec/min)(k calc)(s sec)/(c calc) = 60ks/c sec²/min ≠ min
B. (k calc)(s sec)/(c calc) = ks/c sec ≠ min
C. (k calc)(s sec)/((60 sec/min)(c calc)) = ks/(60c) min . . . correct units
D. (60 sec/min)(c calc)/((k calc)(s sec)) = 60c/(ks) /min ≠ min
E. (k calc)/((60 sec/min)(c calc)(s sec)) = k/(60cs) min/sec² ≠ min
The only choice in which the units work out correctly is choice C.
