If mike read 30 pages an hour how long will it take him to read 1225 pages
Gnesinka [82]

Answer: 2450 min or 40hr and 50 min

Step-by-step explanation:

We can use a proportion to set up this equation.

\frac{30 pages}{60 min} =\frac{1225 pages}{x min}

We cross muliply so get our equation.

30x=1225(60)\\

30x=73500

x=2450 min

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

\frac{60min}{1hr} =\frac{2450min}{x }

60x=2450

x=40 hr 50 min
