Question

If mike read 30 pages an hour how long will it take him to read 1225 pages

Answer 1

Answer: 2450 min or 40hr and 50 min

Explanation:

We can use a proportion to set up this equation.

`(30 pages)/(60 min) =(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

`(60min)/(1hr) =(2450min)/(x )`

`60x=2450`

`x=40 hr 50 min`
