Question

Which of these values represents the longest period of time?
A. 300 minutes
B. 30 hours
C. 0.3 days
D. 30,000 milliseconds

Answer 1

Answer:

30 hours

Step-by-step explanation:

We need to convert these to the same period of time

A. 300 minutes

B. 30 hours

30 hours  * 60 minutes/ 1 hour = 1800 minutes

C. 0.3 days  

.3 days * 24 hours/ 1 day * 60 minutes/ 1 hours =432 minutes

D. 30,000 milliseconds

30 000 ms * 1 seconds/ 1000 ms * 1 minute/60 seconds = .5 minutes

1800 minutes is the longest

Answer 2

300 minutes is only 5hrs
0.3 days is only 7.2 hrs
30,000 milliseconds isn’t even 1hr

B. 30 hours is correct
