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

Answer:

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, $S_{Steven}=\frac{Distance}{time}=\frac{200}{25.7}=7.78\ m/s$

Speed of Michelle is, $S_{Michelle}=\frac{Distance}{time}=\frac{200}{28}=7.14\ m/s$

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.
