Answer
$c=194m/s$
$f=2.5\times 10^{-4} Hz$
$T=4\times 10^3s$
Work Step by Step
We can determine the required speed, frequency and the time period as follows:
First of all, we determine the speed
$c=\frac{x}{t}$
We plug in the known values to obtain:
$c=\frac{3700\times 10^3m}{5.3\times 3600s}$
This simplifies to:
$c=194m/s$
Now the frequency is given as
$f=\frac{c}{\lambda}$
We plug in the known values to obtain:
$f=\frac{194m/s}{750\times 10^3m}$
This simplifies to:
$f=2.5\times 10^{-4} Hz$
and the time period can be calculated as
$T=\frac{1}{f}$
We plug in the known values to obtain:
$T=\frac{1}{2.5\times 10^{-4}}$
$\implies T=4\times 10^3s$
