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?

Answer 1

Ans(1) 167 (rounded off)

ans(2) 32 (rounded off)

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)
