Question

In the qualifying round of the 50-yard freestyle in the sectional swimming championship, Dugan got an early lead by finishing the first 25.00 yards in 10.01 seconds. Dugan finished the return leg (25.00 yard distance) in 10.22 seconds. Determine Dugan's average velocity for the entire race.

Answer 1

Answer:

$V_{average}$=  2.471  yards/s

Explanation:

We can calculate the average velocity thus:

$V_{average} = \frac{D_{1}+D_{2} }{t_{1}+t_{2}}$

Where

              $D_{1}$ : First 25 yards

              $t_{1}$: Time to travel  $D_{1}$

              $D_{2}$ : Seconds 25 yards

              $t_{2}$: Time to travel  $D_{2}$

Thus

$V_{average} = \frac{25 + 25}{10.01 + 10.22}$

$V_{average}$=  2.471  yards/s
