[tex]10\frac{km}{h}=\frac{6.21miles}{h}[/tex]
He covered 31.05 miles in five hours.
Why?
To convert from km/h to mph, we need to convert from km to miles, so:
[tex]1km=0.621miles[/tex]
So, converting the speed, we have:
[tex]10\frac{km}{h}*\frac{0.621mi}{1km}=6.21\frac{mi}{h}=6.21mph[/tex]
Now, calculating how many miles did he bike in 5 hours, we have:
[tex]distance=6.21mph*5h=31.05miles[/tex]
Hence, we have that the cyclist covered a total of 31.05 miles in five hours.
Have a nice day!
