Answer: 75 minutes/1 Hour and 15 minutes/1.25 Hours.
Step-by-step explanation:
If it takes him 10 minutes to read 4 pages, first we should divide 10 by 4 to find out how many minutes it takes for him to read one page.
10 ÷ 4 = 2.5
It takes Mike 2.5 minutes to read each page. Next we just have to multiply 2.5 by 30 to find out how long it takes him to read all 30 pages.
30 × 2.5 = 75
Hope that helps!!
