Respuesta :

given that

[tex]t = 9.87 * 10^8 s[/tex]

we need to convert this time into hours

as we know that

[tex]1 h = 60 min[/tex]

and we also know

[tex]1 min = 60 s[/tex]

so here we have

[tex]1 h = 60 * 60 = 3600 s[/tex]

now we have

[tex]t = 9.87* 10^8 s* \frac{1h}{3600 s}[/tex]

[tex]t = 2.74 * 10^5 h[/tex]

so we can say

[tex]9.87* 10^8 s = 2.74 * 10^5 h[/tex]

Answer:

times 9.87 x 108 and then convert the answer to hours so what would 0.2961 or [tex]10^{5}[/tex]
