Since you're given the rate per minute, you can divide 1.22*10^6 by 1.4*10^3 to see how many minutes it will take then simply divide that by 60 to put it in hours

no. of minutes to fill the pool\[=\frac{ 1.22*10^6 }{ 1.5*10^3 }\]

\[\frac{ 1.22 \times 10^6 }{ 1.5 \times 10^3} \times 1 \min \times \frac{ 1 hr }{ 60 \min }\] we have that 1 minute because it's 1.5*103 in^3/min so then we use our algebra rules to flip and multiply

How did you get 10^4?

Because I settee up the factors and the powers so it's (1.22/ 1.5) (10^6/ 10^3) Divided the factors and got 0.813 0.813 (10^6-^3) I subtracted the exponents and got 3 0.813 × 10^3 The answer has to be in scientific notation so it's 8.13 × 10^4 and added the exponent by 1 to get 4

No it would become 8.13*10^2 then it does not increase

Oh

8.13*10^4 = 81300

0.813*10^3 = 813 = 8.13*10^2

But you want it in hours still, so make sure you divide by 60

So 813/60

13.55 or 13 5/9

Lol it's the same thing, but what ever it's asking for
Astrophysics

Wait no 13.55, 13.55... is 13 5/9
Astrophysics

5/9 would be if the 5555555 was repeating
