Han ran 10 meters in 2.7 seconds. Priya ran 10 meters in 2.4 seconds. a. Who ran faster? Explain how you know. b. At this rate, how long would it take each person to run 50 meters? Explain or show your reasoning.

A) Priya ran faster

B) It would take Han 13.5 seconds and it would take Priya would take 12 seconds

Step-by-step explanation:

They both ran 10 meters, so whoever took a shorter amount of time will be the one that ran faster.

So, Priya ran faster, because she ran 10 meters in a shorter amount of time than Han did.

To find how long it would take each person to run 50 meters, multiply the amount of time it took them by 5, since 50/10 = 5

2.7(5)

= 13.5

2.4(5)

= 12

So, it would take Han 13.5 seconds and it would take Priya would take 12 seconds

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
