Answer 2

$\huge\mathfrak{Answer}$

As we know that, the total distance covered,

s = final reading of odometer- initial reading of odometer

= ( 4460 - 4200) km = 260 km

Total time taken, t = 4 h 20 mins = 4. 33 h

$average \: speed = \frac{total \: distance \: covered}{total \: time \: taken}$

$= \frac{260h}{4.33h} = 60km \: per \: h \: or \: \frac{60 \times 5}{18} = 16.67m m \: per \: sec$

$average \: \: velocity = \frac{total \: displacement}{total \: time \: taken}$

$= \frac{0}{4.33} = 0 \: metre \: per \: sec \:$

So, Average speed of Rajeev is 16. 67 m/s and average velocity is 0.
