Given the speeds of each runner below, determine who runs the fastest. \text{Noah runs 11 feet per second.} Noah runs 11 feet per second. \text{Katie runs 423 feet in 33 seconds.} Katie runs 423 feet in 33 seconds. \text{Jake runs 1 mile in 396 seconds.} Jake runs 1 mile in 396 seconds. \text{Liz runs 638 feet in 1 minute.} Liz runs 638 feet in 1 minute.

Jake

Step-by-step explanation:

Noah: 11 feet per second

Katie: 423 feet / 33 seconds = 12.82 ft/sec (just divide the feet / seconds)

Jake:

1 mile = 5280 feet

Adam runs 5280ft / 396 seconds = 13.34 ft/sec

Liz:

1 minute = 60 second.

Liz runs 638 feet / 60 seconds = 10.63 ft / sec

From the above results we find that Jake runs the fastest

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
