Answer 1

Step-by-step explanation:

Distance travelled by driver = 12393 - 12345

= 48 km

= 48000 m

Time taken by driver = 45 mintues

$speed = \frac{distance}{time} \\ \: \: \: \: = \frac{48000}{45} \\ \: \: \: \: = \frac{3200}{3} \: metre \: per \: second \\ or \: \frac{3200}{3} \times \frac{60}{1000} \: km \: per \: hour \\ or \: 64 \: km \: per \: hour$
