How many pages are there in the book
Sophia is reading a book. On the first day, she reads 1/5 of the pages plus 12 more. On the second day, she reads 1/4 of the remaining pages plus 15 pages. On the third day, she reads 1/3 of the remaining pages plus 18 pages. After this, she has 1/4 of the book left to read. How many pages are there in the book?
To find the average speed, first, calculate the total distance and total time taken.
ReplyDeleteTotal distance: 180 miles + 240 miles = 420 miles
Total time: 3 hours + 4 hours = 7 hours
Now, use the formula for average speed:
Average speed = Total distance / Total time
= 420 miles / 7 hours
= 60 miles per hour
Average speed = 60 miles per hour
