You are driving down the freeway at a speed of 80 mph. You see a sign that says your exit is 2.5 miles away. How long will it take, in minutes, to reach the exit?

Answer :

Answer:

1.875 Minutes

Explanation:

To find the time it will take to reach your exit 2.5 miles away while driving 80 mph, you would use the formula time = distance/rate. Substituting the given values and converting the result from hours to minutes gives you your answer.

The subject of this question is finding out the time it will take you to reach your exit, travelling at a constant speed of 80 mph, when it is 2.5 miles away. In mathematics, specifically in rate questions, it's important to use the formula rate = distance/time. You are looking to find time, so you can rearrange this as time = distance/rate.

Firstly, understand your given situation. You're travelling at a speed of 80 miles per hour (mph), and your total distance to your exit is 2.5 miles. Substituting these values into your formula, you have: time = 2.5 miles / 80 mph.

It will take approximately 1.875 minutes to reach the exit.

To calculate the time it will take to reach the exit, use the formula:

Time = Distance / Speed

Given:

Speed = 80 miles per hour (mph)

Distance to the exit = 2.5 miles

First, calculate the time in hours:

Time (hours) = Distance (miles) / Speed (mph)

Time = 2.5 miles / 80 mph = 0.03125 hours

Since there are 60 minutes in an hour, convert time from hours to minutes:

Time (minutes) = Time (hours) * 60

Time = 0.03125 hours * 60 = 1.875 minutes
