On a scale drawing of a car, 2 inches=5 feet if the car is 15 feet long, how long is the drawing?

Question

anonymous · Answer

6in because 5ft times 3 is 15ft so u would do 2in times three as well to get 6in

anonymous · Answer

2" = 5ft

15/5=3

(3) 2" = (3) 5ft
6" = 15ft

anonymous · Answer

so if 2in =5ft then 6in would= 15ft

You could solve this easily by setting up an equation of ratios:

Actual car length          Scale drawing length

5 ft                                2 in
-----  =                      ------------
15 ft                                x

Cross multiply this equation.  Then solve for x.  x will be in inches.

My answer would be 6? I also had one more question, if I am talking about how long someones front yard is would I use inches or feet?

anonymous · Answer

feet

anonymous · Answer

and yes the answer would be 6 but dont forget the inches symbol so it would be 6in

mathmale · Answer

This produces the same result as others have already obtained:  The 15' long car is represented by a 6" long illustration. 

People do this all the time, but 2" = 5ft is not correct;  2 inches on the diagram corresponds to 5 feet in actual length.

feet. 
inches are too small. 

right so replace the = with :
