5million sales of 30 seconds of ads

Question

If I put 30 seconds of ads onto video content and gain 5 million views (assume all 30 seconds are watched), how many hours of ads have been viewed? I think I've over thought this one and totally messed it up

Answer 1

5 million × 30 ÷ 3600 = 41666.666666666

Answer 2

5 million views * 30 seconds = 150 million seconds

*3600 seconds = 1 hour*

[150 million seconds] / [3600 seconds/hour] = 41,666.66 hours
