मोहन, अनु को 30 मीटर या 10 सैकण्ड़ से हराता है तो मोहन द्वारा 1200 मीटर की दूरी की दौड़ को पूरा करने में कितना समय लगेगा?

Two trains 152.5 m and 157.5m long, running in opposite directions, cross each other in 9.3 seconds. What will be the combined speed of both trains per hour?

Find the speed of the bike in m/sec which covers a distance of $4\times {10}^4$ m in ${10}^{-2}$ seconds.

The distance between two stations, $\mathrm{A}$ and $\mathrm{B}$,is $575 \mathrm{km}$. A train starts from station $\text{'}\mathrm{A}\text{'}$at $3:00 \mathrm{p}.\mathrm{m}.$and moves towards station $\text{'}\mathrm{B}\text{'}$ at an average speed of $50 \mathrm{km}/\mathrm{hr}$.Another train starts from station $\text{'}\mathrm{B}\text{'}$at $3:30 \mathrm{p}.\mathrm{m}.$and moves towards station $\text{'}\mathrm{A}\text{'}$ at an average speed of $60 \mathrm{km}/\mathrm{hr}$.How far from station $\text{'}\mathrm{A}\text{'}$ will the trains meet?

An object travels $20$ meters in $4$ seconds and $15$ meters in the next two seconds. What is the average speed of the object?
