Jim is standing outside on a sunny evening at 6{“version”:”1.1″,”math”:”6″} pm.  Jim’s shadow at that time is 12.4{“version”:”1.1″,”math”:”12.4″} feet long.  A flagpole near Jim is 22.4{“version”:”1.1″,”math”:”22.4″} feet tall and also casts a shadow.  If Jim is 6.1{“version”:”1.1″,”math”:”6.1″} feet tall, how long is the shadow cast by the flagpole in feet?  Round your answer to the nearest tenth.
