Explain which is faster: 10 centimeters/5 seconds or 10 centimeters/20 seconds.
2 answers:
Answer:
10 centimetre / 5 seconds
Step-by-step explanation:
10 cm / 5 sec means that you are travelling 10 cm every 5 seconds. Or 2 cm every 1 seconds. ( Divide by 5).
10 cm / 20 seconds means that you are travelling 10 cm every 20 seconds. Or 0.5 cm ever 1 second. (Divide by 20)
10 centimeters/5 seconds would be faster because even though they traveled the same distance, this one did it in a shorter amount of time. They only took 5 seconds to go 10 centimeters, while the other took 20.
