Question

On a road trip, Andrew plans to use his cruise control for 125 mi, plus or minus 20 mi. What is the possible range of distances Andrew might travel using cruise control?

a) 105 mi to 145 mi
b) 105 mi to 165 mi
c) 105 mi to 125 mi
d) 125 mi to 145 mi

Answer 1

The possible range of distances Andrew might travel using cruise control is from 105 miles to 145 miles.

Step-by-step explanation:

The student asked about the range of distances Andrew might travel using cruise control. Andrew plans to use his cruise control for 125 miles, plus or minus 20 miles. The range of distances Andrew might travel is calculated as follows:

• The minimum distance is 125 mi - 20 mi which equals 105 mi.
• The maximum distance is 125 mi + 20 mi which equals 145 mi.

Thus, the possible range of distances that Andrew might travel using cruise control is from 105 miles to 145 miles, which corresponds to option (a) 105 mi to 145 mi.
