Answer:
(a) [tex]43.45\frac{km}{h}[/tex]
(b) [tex]12.08\frac{m}{s}[/tex]
Explanation:
(a) 1 mile is equal to 1.609344 kilometers. So, we have:
[tex]27\frac{mi}{h}*\frac{1.609344 km}{1mi}=43.45\frac{km}{h}[/tex]
(b) 1 mile is equal to 1609.34 meters. 1 hour is equal to 3600 seconds. So, we have:
[tex]27\frac{mi}{h}*\frac{1609.34m}{1mi}=4.35*10^{4}\frac{m}{h}\\4.35*10^{4}\frac{m}{h}*\frac{1h}{3600s}=12.08\frac{m}{s}[/tex]
