Question

In downtown Chicago, the east-west blocks are 400 ft long while the north-south blocks are 280 ft long. Because of the many one-way streets, it can be challenging to get around. Veronica starts at the corner of Dearborn and Ohio Streets. She drives four blocks north to Superior, two blocks east to Wabash, then a block south to get to her destination at Wabash and Huron.
Required:
What is the straight-line distance from her starting point?

Answer 1

Answer:

The answer is "1160 ft".

Explanation:

Using the Pythagoras theorem:

$\to a= 280 \times 3= 840\\\\\to b= 400 \times 2= 800$

$\bold{\to y^2= a^2+b^2}$

         $=840^2 +800^2\\\\= 705600+640000\\\\=1345600\\\\=1160 \ ft$

  $\to y=1160 \ ft$
