Science and technology: electric vehicles and solar energy

Read the following text and perform the requested tasks: 'By the year $2050$, the implementation of advanced electric propulsion systems is expected to reduce urban pollution. An electric vehicle travels at an average speed of $60 \text{ km/h}$ for a duration of $2.5 \text{ hours}$. Calculate the total distance ($d$) covered by this vehicle. Furthermore, explain why the use of solar energy, represented as $E_{solar}$, is considered a better alternative to burning fossil fuels which release $CO_2$ into the atmosphere.'
