If Susan can read 40 pages in 12 minutes, how many pages can she read in 50 minutes? The key on a map says 2 inches equals 7 miles. If two cities are9 inches apart on the map, how far apart are they in real life?

We change it so that we know how much she reads in 1 minute.

So 40÷12=3.33333333

We want to know 50 minutes, so

3.33333333×50=166.666666

Giving us a full 166 pages she can read in 50 minutes

So 2 map inches = 7 real life miles

So 1 map inch = 3.5 real life miles

So 9 map inches = 31.5 real life miles

Ans(1) 167 (rounded off)

ans(2) 32 (rounded off)

Step-by-step explanation:

1. Pgs read in 12 mins= 40

  Pgs read in 1 min= 40/12 =10/3

  Pgs read in 50 mins= 10/3 ×50= 166.6

So, when rounded off, Susan can read 167 pgs in 50 mins./ (ans)

2. 2 inches distance= 7 miles

   1 inch distance= 7/2 miles

    9 inches distance= 7/2 × 9= 31.5

so, when rounded off, the cities are 36 miles apart in real life/ (ans)
