Lakhmir Singh and Manjit Kaur Solutions for Chapter: Motion and Time, Exercise 2: Short Answer Type Questions

An ant covers 1 $\mathrm{metre}$ distance in $10$$\mathrm{seconds}$. What is the speed of the ant in $\mathrm{cm}/\mathrm{s}$?

In an experiment to measure the speed of a moving ball, it is observed that the ball covers a distance of $5 \mathrm{m}$ and $20 \mathrm{c}\mathrm{m}$ in $4$ seconds before it comes to a stop. Calculate the speed of the ball in$\mathrm{m}/\mathrm{s}$.

The speed of a racing car is $60 \mathrm{m}/\mathrm{s}$. What will this speed be in $\mathrm{k}\mathrm{m}/\mathrm{h}$?
