Answer:
[tex]19.2\times 10^8\ minutes[/tex] in hour is:
[tex]3.200 \times 10^7\ h[/tex]
Step-by-step explanation:
1 hour=60 minutes
⇒ 1 minute=[tex]\dfrac{1}{60}[/tex] hour
⇒ [tex]19.2\times 10^8\ minutes=\dfrac{1}{60}\times 19.2\times 10^8\ hour[/tex]
⇒ [tex]19.2\times 10^8\ minutes=3.200 \times 10^7\ hour[/tex]
Hence, [tex]19.2\times 10^8\ minutes[/tex] in hour is:
[tex]3.200 \times 10^7\ h[/tex]
