Luis traveled uphill to the hardware store for 30 at just 8mph. He then traveled back home along the same path downhill at a speed of 24 mph what is his average speed for the entire tip from home to the hardware store and back

Step-by-step explanation:

We have been given that Luis traveled uphill to the hardware store for 30 minutes at just 8 mph.

Let us find distance traveled by Luis using distance formula.

30 minutes are equal to 0.5 hour or 1/2 hour.

Let us find time taken while traveling 4 miles at a rate of 24 mph.

Therefore, the average speed is 12 miles per hour.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
