Red car
blue car
Both have same speed

Answer 1

Answer:

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

Answer:

Explanation:

Let n be 1/5th of the distance covered. Then the first part is 2n long, and the second part is 3n long. The total time taken to cover these lengths is:

2n/80 + 3n/60

And the total distance is 5n. So, the average velocity is the total distance over the total time. Like this:

V=5n/ 2n/80 + 3n/60

=1200n/6n+12n

=1200/18

=66 2/3 km/h

meaning the blue  car is faster
