B. Blue car
C. Both have equal speed
D. All of these.
justify your answer

Answer 1

$20 km\times 1000 = 20000m$
$20min \times 60 = 1200sec$
$20000 \div 1200 = 17km \: per \: hr \: approx.$
$200 \div 20 = 10km \: per \: hour$
therefore blue car has greater speed... if u like my answer then mark me the brainliest

Answer 2

speed = distance divided by time

so, red cars speed is equal to 200 divided by 20. so the speed is 10m/s

20 km =20000 mts then 20 mins = 1200 secs.

blue cars speed is equal to 20000 mts divided by 1200 is 16.6m\s. so blue car has more speed.
