Correct the following.
$90 \mathrm{m}.$

(Fill the space with the correct way to write the distance)

Correct the following.
$100 \mathrm{k}\mathrm{g}\mathrm{s}$

Write the following with its correct unit symbol.
$10 \mathrm{s}\mathrm{e}\mathrm{c}\mathrm{s}$

Correct the following.
$50 \mathrm{k}\mathrm{i}\mathrm{l}\mathrm{o}$

The distance between two towns is $400 \mathrm{k}\mathrm{m}$. How much time would it take a car to cover this distance at an average speed $50 \mathrm{k}\mathrm{m}/\mathrm{h}$?

A man driving at an average speed of $40 \mathrm{k}\mathrm{m}/\mathrm{h}$ takes $6$ hours to travel from one town to another. What is the distance between the towns?

Plot a distance-time graph for a body travelling at a speed of $2.5 \mathrm{m}/\mathrm{s}.$

The distance covered by a moving body over time is represented graphically in figure. Find its speed.
