Question

Mike reads 60 pages in 1 and ½ hours. How many pages would he read in 120 minutes.

A. 80 pages
B. 100 pages
C. 120 pages
D. 40 pages

Answer 1

Answer: (A) 80 pages

Explanation:

60 pages to 1 and ½ hours

x pages to 120 minutes

Change 1 and ½ hourst to minutes

1 and ½ hours= 90 minutes

60 pages = 90 minutes

x pages = 120 minutes

x*90=60*120

x=60*120/90

x=80 pages

Answer 2

80 pages

Explanation:

recall that there are 60 min in an 1 hour

hence in 1 1/2 hrs, there will be:

60 x 1-1/2

= 60 x (3/2)

= 90 min

It is given that mike reads 60 pages in 1 1/2 hrs (i.e 90 min), hence

90 min--------> 60 pages

1 min -------> 60/90 pages

120 min -------> (60/90) x 120 = 80 pages
