Brian can read 80 pages in 2 hours. How many pages can he read in 3.5 hours? (1 point) Responses 140 pages 140 pages
560 pages 560 pages 11.43 pages 11.43 pages 45.71 pages
To find out how many pages Brian can read in 3.5 hours, we need to set up a proportion.
The proportion can be set up as:
80 pages / 2 hours = X pages / 3.5 hours
Using cross multiplication, we can solve for X.
2 hours * X pages = 80 pages * 3.5 hours
2X = 280
Dividing both sides of the equation by 2, we find:
X = 140
Therefore, Brian can read 140 pages in 3.5 hours.
To find out how many pages Brian can read in 3.5 hours, we can set up a proportion using the information given.
Since Brian can read 80 pages in 2 hours, we can say that the ratio of pages read to hours is 80:2.
To find out how many pages he can read in 3.5 hours, we can set up a proportion:
80/2 = x/3.5
To solve for x, we can cross multiply:
2x = 80 * 3.5
2x = 280
x = 280/2
x = 140
Therefore, Brian can read 140 pages in 3.5 hours.
To determine how many pages Brian can read in 3.5 hours, we can use a proportion to find the answer.
We know that Brian can read 80 pages in 2 hours. We can set up the proportion:
80 pages / 2 hours = x pages / 3.5 hours
To solve for x, we can cross-multiply and then divide:
80 * 3.5 = 2 * x
280 = 2x
Dividing both sides by 2:
x = 140 pages
So, Brian can read 140 pages in 3.5 hours. Therefore, the correct answer is 140 pages.
