![10(km)/(h)=(6.21miles)/(h)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/qf1voobwhfcidj0ywwxakm0to4c9vggsw8.png)
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:
![1km=0.621miles](https://img.qammunity.org/2020/formulas/mathematics/middle-school/p97plulz4ik20t3dphes2fvkfzeak72acq.png)
So, converting the speed, we have:
![10(km)/(h)*(0.621mi)/(1km)=6.21(mi)/(h)=6.21mph](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2a1v0o06mt88awbgnabx4up59222ibcjmu.png)
Now, calculating how many miles did he bike in 5 hours, we have:
![distance=6.21mph*5h=31.05miles](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ajjdu7gcrc447vr1llbkrj6014jdg7t47g.png)
Hence, we have that the cyclist covered a total of 31.05 miles in five hours.
Have a nice day!
