Find the ratio of speed of car which us 20 m per second to the speed of car which id 72 km per hour
Answers
Answer: 1:1
Step-by-step explanation:
Ratio: The relation between two quantities which shows how much bigger one quantity is than another.
Speed: The rate at which an object moves in a particular direction.
As we all know ratios can be compared only if the quantities to be compared are of the same units.
Here, the quantities to be compared are 20 m/s and 72 km/h.
Now, 1 km/h = 1000m/3600s = 5m/18s
Therefore, to convert km/h into m/s the value needs to be multiplied by 5/18.
Therefore the quantities now are:-
20m/s and (72×5/18)m/s
=> 20m/s and 20m/s
Now, ratios can be written in the form of a:b where 'a' and 'b' are non-zero integers.
Therefore, the ratio of the speed of the cars is 20:20 or 1:1.
Hope it helps!
Answer:
answer is 20:20 because 1km is equal to 1000m
