Answer 1

attachment is self explanatory

Answer 2

"Total distance covered from Lucknow to Jamshedpur be ‘x’

Half the distance was covered by train means $\frac { x }{ 2 }$ with the speed of 96Km/hr

Half the distance by the scooter ‘$\frac { x }{ 4 }$’ with the speed of 60Km/hr

Remaining distance ‘$\frac { x }{ 4 }$’ aped by car with 40Km/hr

Average speed = total distance/time taken

Average speed =$\frac {x}{(\frac {x}{ \frac {2}{96}})+(\frac {x}{ \frac {4}{60}})+(\frac {x}{ \frac {4}{40}})}$

By simplifying the above equation we get, 64Km/hr

The average speed at the he completed his journey is 64Km/hr"
