Initial reading = 24803 km
Final reading = 25118 km
The speedometer reading at the start of the journey and at the end of the journey was noted by Kamini and the total time was also noted, the average speed is given by,
Total time = 4 hr and 40 min
{tex}Average \ speed = \frac {Total \ distance}{Total \ time}{/tex}
Total distance = Final reading – Initial reading
Total distance = 25118 – 24803
Total distance = 315 km
Total time = 4 hr 40 min
{tex}Total\ time = 4hr + (\frac {40}{60}) hr{/tex}
Total time = 4.67 hr
{tex}Average \ speed = \frac {315}{4.67}{/tex}
Average speed = 67.45 km/hr
