Brian can read 80 pages in 2 hours. How many pages can he read in 3.5 hours?
To find the number of pages Brian can read in 3.5 hours, we need to find his reading rate per hour.
Brian reads 80 pages in 2 hours, so his reading rate is 80 pages / 2 hours = <<80/2=40>>40 pages/hour.
To find the number of pages Brian can read in 3.5 hours, we multiply his reading rate by the number of hours:
40 pages/hour * 3.5 hours = <<40*3.5=140>>140 pages.
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 proportional relationship using the given information.
Brian can read 80 pages in 2 hours.
Let's set up the proportion:
80 pages / 2 hours = x pages / 3.5 hours
To solve for x, we can cross multiply and divide:
2 * x = 80 * 3.5
2x = 280
x = 280 / 2
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.
We know that Brian can read 80 pages in 2 hours. Let's define a variable for the number of pages he can read in 3.5 hours. Let's call this variable x.
Proportion: 80 pages / 2 hours = x pages / 3.5 hours
To solve for x, we can cross-multiply and then divide:
2 hours * x pages = 80 pages * 3.5 hours
2x = 280
Now, divide both sides of the equation by 2:
2x / 2 = 280 / 2
x = 140
Therefore, Brian can read 140 pages in 3.5 hours.
