a. The minimum number of minutes it will take you to travel to school is 27 minutes
b. The maximum number of minutes it will take you to travel to school is 33 minutes
<h3>How to find the minimum and maximum number of minutes it will take you to travel to school?</h3>
Since the drive to school is about 12.5 miles, but the distance varies by up to 1.25 miles.
The distance is given by d = 12.5 ± 1.25 miles
<h3>a. What is the minimum number of minutes?</h3>
Now the minimum distance to school is d' = 12.5 - 1.25 miles = 11.25 miles
Since you are driving at a constant speed of v = 25 mph, the time it takes to cover this minimum distance to school is t = d'/v = 11.25 miles/25 mph = 0.45 h
Converting this to minutes, we have t = 0.45 × 60 min = 27 minutes
So, the minimum number of minutes it will take you to travel to school is 27 minutes
<h3>b. What is the maximum number of minutes?</h3>
Now the maximum distance to school is d" = 12.5 + 1.25 miles = 13.75 miles
Since you are driving at a constant speed of v = 25 mph, the time it takes to cover this maximum distance to school is t = d'/v = 13.75 miles/25 mph = 0.55 h
Converting this to minutes, we have t = 0.55 × 60 min = 33 minutes
So, the maximum number of minutes it will take you to travel to school is 33 minutes
