part c
express your answer in seconds.
1.0 year =

Explanation:

Step1: Recall time - unit conversion

1 hour = 60 minutes, 1 minute = 60 seconds.

Step2: Calculate seconds in 1 hour

$1.0$ hour $\times60$ minutes/hour $\times60$ seconds/minute = 3600 seconds.

Step3: Calculate seconds in 1 day

1 day = 24 hours. So $1.0$ day $\times24$ hours/day $\times60$ minutes/hour $\times60$ seconds/minute = 86400 seconds.

Step4: Calculate seconds in 1 year

Assume 1 year = 365 days. Then $1.0$ year $\times365$ days/year $\times24$ hours/day $\times60$ minutes/hour $\times60$ seconds/minute = 31536000 seconds.

Answer:

Part A: 3600
Part B: 86400
Part C: 31536000
