An object moves $360 \mathrm{km}$ in $2$ hours. Calculate its speed in $\mathrm{km}/\mathrm{h}$ and $\mathrm{m}/\mathrm{s}$.

Kushal loves to visit his grandparents every year to spend his summer holidays with them. They live in a remote village. He takes a train, then a bus and then, walks the rest of the journey. The train travels at $60 \mathrm{km}/\mathrm{h}$ for $5$ hours, the bus travels at $40 \mathrm{km}/\mathrm{h}$ for $3$ hours and he walks at a speed of $5 \mathrm{km}/\mathrm{h}$ for $1$ hour. What is the total distance he travels from the railway station to his grandparents' house?
