Astudent runs 100 meters in 11 seconds. what is the speed of the student? (2 points) speed = distance over time ; 1 mile = 1609 meters

The equation for speed is:

The student ran 100 meters in 11 seconds. Our distance is 100 meters and our time is 11 seconds.

When we solve we get the following:

I am guessing since you were given the unit conversion of 1 mile = 1609 meters, you need to answer in miles per hour. If you do, you will need to use dimensional analysis:

All of the units except miles and hour cancel out, which makes this problem valid. Your answer in mph (mi/hr) would be:

20.34 miles per hour

the correct answer is 5 6 and 7

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
