Question

find that ratio for speed of car which is 20m per second thought the speed of car which is 72km per hour

Answer 1

Answer:

1:1

Step-by-step explanation:

speed of 1 = 20 m/s

speed of 2 = 72 km/hr

= 72000 m/hr

=72000 /3600 m/s

= 20 m/s

ratio = 1:1

Answer 2

Answer:

Step-by-step explanation:

Km/hr=m/s×18/5

= 20m/s×18/5

=72km/hr is the speed of first car

Given,

Speed of second car =72km/hr

Ratio=speed of first car/speed of second car

=72/72

=1/1=1:1
