Dave's Average Speed=320 ft/min.

Distance = Average Speed X Time

In 1 minute, their distances from their starting point is determined below.

Alice's Distance=280 X 1=280ft

Dave's Distance= 320 X 1=320ft

Since they walk in opposite direction, their distance from each other will be the sum of their distances from the starting point.

Distance of Alice from Dave=280+320=600 ft

10) Use the graph below: What percent of strikeouts is Samar responsible 10 pointsfor?BASEBALL STRIKEOUTSCARLOSPITCHERYUSAMARJUS
JulsSmile [24]

First let's find out the total number of strikeouts, by adding the number of strikeouts of each person:

\text{total}=13+9+5+11+8+4=50

Now, to find the percentage of strikeouts that Samar is responsible, let's divide his number of strikeouts (5) by the total number of strikeouts (50):

\frac{5}{50}=\frac{1}{10}=\frac{10}{100}=10\text{\%}

So Samar is responsible for 10% of the strikeouts.
