20 POINTS PLEASE HELP, AND FAST A mule deer can run one over four of a mile in 25 seconds. At this rate, which expression can be used to determine how fast a mule deer runs in miles per hour?

A twenty-five seconds over one-fourth mile = 36 miles per hour
B one-fourth mile over twenty-five seconds = 36 miles per hour
C one-fourth mile over twenty-five seconds = 100 miles per hour
D twenty-five seconds over one-fourth mile = 100 miles per hour

1/4 mile over 25 seconds= 36 miles

The way we work this out is by working out the amount of lots of 25 seconds in an hour, and then multiply it by that 1/4 of an hour. 1 hour has 60 minutes, and each minute has 60 seconds, so 1 x 60 x 60 = 3600 = the number of seconds in an hour.

3600/25 = 144. Therefore there are 144 lots of 25 seconds in an hour. If the deer runs 1/4 a mile in 25 seconds, then we just have to do 144 x 1/4 and it will give us the answer.

144 x 1/4 = 36. Therefore the deer can run 36 miles per hour.

If you want to express this all in one equation, we can write it as:

((60 x 60)/25) x 1/4 = 36

Hope this helped :))

B one-fourth mile over twenty-five seconds = 36 miles per hour

3600 seconds in 1 hour

3600/25=144

144×.25=36

I hope this is good enough:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
