1df 11. Simon usually drove to work at an average speed of \( 72 \mathrm{~km} / \mathrm{h} \). On Monday, he left his home 10 minutes later than usual and had to drive at \( 90 \mathrm{~km} / \mathrm{h} \) in order to reach his office at the usual time. How far is his house from his office? \[ 90-72=18 \mathrm{~km} / \mathrm{h}=10 \mathrm{~min} \]
