Answer:
1.33 × 10² hours
Step-by-step explanation:
Time taken is calculated as
Time = [tex]\frac{Distance}{Speed}[/tex]
= [tex]\frac{3.2(10^{6}) }{2.4(10^{4}) }[/tex]
= [tex]\frac{3.2}{2.4}[/tex] × [tex]\frac{10^{6} }{10^{4} }[/tex]
= 1.33 × [tex]10^{(6-4)}[/tex]
= 1.33 × 10² hours ( to 3 significant figures )
