Question
Melissa is driving along a highway at a constant speed of 65 miles per hour.How long does it take her to travel 90 miles? Make sure to convert the answer into hours and minutes.An hour and 48 minutesAn hour and 18 minutesAn hour and 33 minutesAn hour and 23 minutes
Solution
To solve this problem, we need to use the formula for time which is distance divided by speed.
Step 1: Identify the given values. The distance (d) Melissa needs to travel is 90 miles and her speed (s) is 65 miles per hour.
Step 2: Substitute the given values into the formula. Time (t) = d/s t = 90 miles / 65 miles per hour t = 1.3846 hours
Step 3: Convert the decimal part of the hour into minutes. To do this, take the decimal part and multiply by 60 (since there are 60 minutes in an hour). 0.3846 hours * 60 minutes/hour = 23.08 minutes
So, it will take Melissa approximately 1 hour and 23 minutes to travel 90 miles at a constant speed of 65 miles per hour. Therefore, the correct answer is "An hour and 23 minutes".
