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]
