Joe is the owner and CEO of Pinecrest Enterprises, a real estate development company in Boise, Idaho. The company has taken on a new development project outside of town, and Joe wants to drive out to survey the proposed development site. The site is 30 miles away from Joe’s office. Setting a good example, Joe drives the speed limit of 45 miles per hour to the development site and back.
What is your question?
To determine how long it will take for Joe to drive to the development site and back, we need to use the formula:
Time = Distance / Speed
First, let's calculate the time it will take for Joe to drive to the development site.
Distance = 30 miles
Speed = 45 miles per hour
Time to drive to the development site = Distance / Speed = 30 miles / 45 miles per hour
To divide 30 miles by 45 miles per hour, we can convert the denominator (45 miles per hour) to miles per minute by dividing it by 60 (since there are 60 minutes in an hour).
45 miles per hour = 45 miles / 60 minutes = 0.75 miles per minute
Now we can divide 30 miles by 0.75 miles per minute.
30 miles / 0.75 miles per minute = 40 minutes
It will take Joe approximately 40 minutes to drive to the development site.
Similarly, to find the time for Joe to drive back to his office, we can use the same formula:
Time = Distance / Speed
Distance = 30 miles
Speed = 45 miles per hour
Time to drive back to the office = Distance / Speed = 30 miles / 45 miles per hour
Again, we'll convert the denominator to miles per minute by dividing it by 60.
45 miles per hour = 0.75 miles per minute
Now we can divide 30 miles by 0.75 miles per minute.
30 miles / 0.75 miles per minute = 40 minutes
It will take Joe approximately 40 minutes to drive back to his office.
Therefore, Joe's round trip to the development site will take about 40 minutes each way, totaling to 80 minutes (or 1 hour and 20 minutes) in total.
