Each week, rosario drives to an ice skating rink that is 60 miles away. the round-trip takes 2.75 hours. if he averages 55 miles per hour on his way to the rink, which equation can be used to find x, the number of miles per hour he averages on his way home?

He averages 36.14 miles per hour on his way home

Step-by-step explanation:

Given:

Rosario drives to an ice skating rink that is 60 miles  round-trip takes 2.75 hours. If he averages 55 miles per hour on his way to the rink

To Find: Find out the number of miles per hour he averages on his way home

Solution:

Total time taken for the trip = 2.75 hours

FIRST CASE : Rosario on his way to the rink

distance traveled to ice skating rink = 60 miles  

average miles per hour on his way to the rink = 55 miles per hour

So, time taken on his way to rink  =

SECOND CASE: Rosario on his way to the home

Distance traveled to the home = 60 miles

Let Average miles per hour on his way to the home =  x

So, time taken on his way to the home =  

Since the total time was 2.75 hours

⇒

⇒

⇒

⇒

⇒

Thus , He averages 36.14 miles per hour on his way home

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
