Question

if parts per million was expressed as time, it would be equal to 1 second every how many days? other 1/2 1.1 1

Explanation:

Step1: Calculate seconds in a day

A day has 24 hours, 1 hour has 60 minutes, 1 minute has 60 seconds. So seconds in a day: $24\times60\times60 = 86400$ seconds.

Step2: Find days for 1 million seconds

We need to find how many days are in 1,000,000 seconds. Divide 1,000,000 by seconds per day: $\frac{1000000}{86400}\approx11.57$ days, approximately 11.5 or 11 - 12 days. But looking at options, "11" is a close approximation (maybe rounding or approximate calculation). Wait, let's re - check. Wait, parts per million: 1 second per x days means that 1 second is 1/1000000 of x days' seconds. So x days' seconds = 1000000 seconds. x = 1000000 / (246060)=1000000/86400≈11.57, so approximately 11 or 12. Among the options, 11 is there.

Answer:

11 (assuming the option "11" is the correct choice for the approximate value as the exact is ~11.57)
