Question

Steven swam 200 meters in 25.7 seconds while Michelle finished in 28 seconds. How much faster did Steven swim than Michelle?

Answer 1

Steven swam 200 meters 2.3 seconds faster than Michelle by completing the distance in 25.7 seconds compared to Michelle's 28 seconds.

Step-by-step explanation:

To determine how much faster Steven swam than Michelle, we calculate the difference between their times. Steven's time to swim 200 meters is 25.7 seconds, and Michelle's time is 28 seconds. The difference in time is:

28 seconds - 25.7 seconds = 2.3 seconds

Therefore, Steven swam 200 meters 2.3 seconds faster than Michelle.

Answer 2

Steven is faster than Michelle by covering 0.64 meters more per second than that of Michelle.

Step-by-step explanation:

Given:

Steven swam 200 m in 25.7 seconds while Michelle finished in 28 seconds.

So, speed of Steven is,
`S_(Steven)=(Distance)/(time)=(200)/(25.7)=7.78\ m/s`

Speed of Michelle is,
`S_(Michelle)=(Distance)/(time)=(200)/(28)=7.14\ m/s`

Now, to find how much faster did Steven swim than Michelle, we need to get the difference between their speeds.

Speed of Steven - Speed of Michelle

`7.78-7.14`

`=0.64\ m/s`

So, Steven is faster than Michelle by covering 0.64 meters more per second than that of Michelle.
