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

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

$60x=2450$

$x=40 hr 50 min$
