For an experiment in Botany, two different plants, plant $A$ and plant $B$ were grown under similar laboratory conditions. Their heights were measured at the end of each week for $3$ weeks. The results are shown by the following graph.

How high was Plant $A$ after (i) $2$ weeks (ii) $3$ weeks?

The following graph shows the temperature forecast and the actual temperature for each day of a week.

On which days was the forecast temperature the same as the actual temperature.

A courier-person cycles from a town to a neighbouring suburban area to deliver a parcel to a merchant. His distance from the town at different times is shown by the following graph.

If the distance of the place of merchant from the town is $x \mathrm{km}$, write $x$ as the final answer.

A courier-person cycles from a town to a neighbouring suburban area to deliver a parcel to a merchant. His distance from the town at different times is shown by the following graph. If he rides fastest during $t \mathrm{a}.\mathrm{m.}$ to $\left(t+1\right) \mathrm{a}.\mathrm{m.}$ find $t$?
