24 h/day x 3,600 s/h x 365 day/yr?

Question

24 h/day x 3,600 s/h x 365 day/yr?

Answer 1

= number of seconds in a year

Answer 2

Step 1.   Multiplying 3600 s/h by 24 h/day the h units cancel and we have:  86,400 s/day

Step 2.  Multiplying 86,400 s/day by 365 day/yr the day units cancel and we have:  31,536,000 s/yr

So we have 31,536,000 s in a year.  What is not shown is that there are 60 s/min and 60 min/h.  Upon multiplying these the min units cancel and we get 3600 s/h.

Answer 3

32536000
