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.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
