Answer: 2450 min or 40hr and 50 min

Step-by-step explanation:

We can use a proportion to set up this equation.

[tex]\frac{30 pages}{60 min} =\frac{1225 pages}{x min}[/tex]

We cross muliply so get our equation.

[tex]30x=1225(60)\\[/tex]

[tex]30x=73500[/tex]

[tex]x=2450 min[/tex]

It took Mike 2450 min to read 1225 pages. We can also use a proportion to write this in hours

[tex]\frac{60min}{1hr} =\frac{2450min}{x }[/tex]

[tex]60x=2450[/tex]

[tex]x=40 hr 50 min[/tex]
