PLEASE EXPLAIN THE ANSWER

Answer 1

Ok last week she walked 18/6 which equals 3 and 3 is less than 2.5. 2.5h is really just that times how many hours.D is the amount of miles.So,the awnser is going to  be b or d.But we dont know what d is in d=2,5h so we have to asume that b is the awnser

Answer 2

Answer:

Last week, she walked a greater distance

Step-by-step explanation:

Rosemary walks each week for exercise. Let d represent the distance walked and h represent the number of hours spent walking.

Last week: walked 18 miles in 6 hours

Rosemary walked (18/6) = 3 miles per hour

This week: d = 2.5h

This week she walked 2.5 miles per hour

last week she walked 3 miles per hour that is greater than 2.5 miles per hour

So , Last week, she walked a greater distance
