Question 1:

A tractor can complete its journey in 10 hours at the speed of $36 \mathrm{~km} / \mathrm{hr}$. If the same distance is to be covered in 8 hours, what should be the speed of the tractor?

Question 2:

Kiran swims in a $90 \mathrm{~m}$ long pool. She covers $360 \mathrm{~m}$ in two minutes by swimming from one end to the other and back along the same straight path, twice. Find the average speed of Kiran.

Question 3:

A student covers a distance of $420 \mathrm{~km}$ in 7 hours. He covered some time at $75 \mathrm{~km} / \mathrm{hr}$ and the rest at $55 \mathrm{~km} / \mathrm{hr}$. For how much time did he cover the distance at high speed?

Question 4:

An object travels $10 \mathrm{~m}$ in $4 \mathrm{~s}$ and then another $14 \mathrm{~m}$ in $2 \mathrm{~s}$. What is the average speed of the object?

Question 5:

Walking at the speed of $10 \mathrm{~km} / \mathrm{hr}$, Madhu reached her university 15 minutes late. Next time she increases her speed by $2 \mathrm{~km} / \mathrm{hr}$, but still she reaches 5 minutes late. What is the distance of the university from his home?

Question 6:
