## Question 1:

A train running at $54 \mathrm{~km} / \mathrm{h}$ crosses a pole in 20 seconds. How much time (in seconds) will it take to cross a bridge $375 \mathrm{~m}$ long?

## Question 2:

Two trains started running from the same point at the same time in opposite directions. The speed of the two trains are 8 m/s and 7 m/s respectively. How much time will they take to be 189 km apart? (in hours)

## Question 3:

A bus covers a certain distance in 4 hour. If speed of bus reduced to $40 \mathrm{~km} / \mathrm{h}$, then it will take 1 hour more to cover the same distance. Then find the difference (in hours) between usual time and time taken by bus after increasing the usual speed by $100 \%$.

## Question 4:

The distance between two places $\mathrm{A}$ and $\mathrm{B}$ is $1090 \mathrm{~km}$. A train starts from $\mathrm{A}$ at $50 \mathrm{kmph}$ at 6 am and another train starts from B at 80 $\mathrm{kmph}$ at 7 am towards each other. At what time will they meet?

## Question 5:

A person covers a certain distance with certain speed if he increases his speed by $30 \mathrm{~km} / \mathrm{hr}$, then he will be $32 \mathrm{~min}$. early. By how much time he will be late if he reduces his speed by $24 \mathrm{~km} / \mathrm{hr}$, if his initial speed is $120 \mathrm{~km} / \mathrm{hr}$?

## Question 6:

A 270 metres long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train?

## Question 7:

Mahima, starting her journey 12 minutes late than usual, has to travel at a speed of $54 \mathrm{~km} / \mathrm{h}$ instead of $45 \mathrm{~km} / \mathrm{h}$ to reach the destination on time. What is the distance covered during the journey?

## Question 8:

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 9:

An object travels $25 \mathrm{~m}$ in $3 \mathrm{~s}$ and then $15 \mathrm{~m}$ in $2 \mathrm{~s}$. What is the average speed of the object?

## Question 10:

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?
