Answer:
a) [tex]16.45 \frac{m}{s}[/tex] b) [tex]36.94 \frac{mi}{h}[/tex]
Explanation:
The average speed is given by the formula: [tex]\frac{distance}{time}[/tex]
The distance covered is 2011.25m , and the time is 122.2s.
Replacing in the formula: [tex]speed_{avg} = \frac{2011.25 m}{122.2s}[/tex]
Resulting in a) [tex]speed_{avg} = 16.45 \frac{m}{s}[/tex].
To get the result in mi/h, do the following conversion:
Knowing : 1 mi = 1603 m and 1 h = 3600 seg
-
[tex]16.45\frac{ m}{s}*(\frac{1mi}{1603m } ) *(\frac{3600s}{1h} ) = 36.94\frac{mi}{h}[/tex]
