Answer 1

AVERAGE SPEED:

WHEN THE TRIP START

$\frac{distance}{time}$

$\frac{3000 \: km}{10 \: hrs}$

$= 300 \: km \: per \: hour$

$= 300 \: \times \: 1000 \: meter \: per \: hour$

$300000 \:meter \: per \: hour$

AT THE END OF THE TRIP

$\frac{3500 \: km}{10 \: hrs}$

$350 \: km \: per \: hour$

$350 \: \times \: 1000 \: meter \: per \: hour$

$350000 \: meter \: per \: hour$
