Final answer:
Mandy traveled a distance of 3/5 miles.
Step-by-step explanation:
Mandy spent a total of 75 minutes (1 hour and 15 minutes) walking three miles. The next day, she walked for 1/4 hour, which is equivalent to 15 minutes.
Since Mandy walked at the same rate as the previous day, we can assume that her speed remained constant. Therefore, we can use the formula Distance = Speed x Time to find the distance she traveled.
Distance = Speed x Time = 3 miles x (15 minutes / 75 minutes) = 3 miles x 1/5 = 3/5 miles
So, Mandy traveled a distance of 3/5 miles.
