Question

A hot air balloon is rising at a rate of 40 meters per minute. How fast is it rising in feet per second? Use conversion factors and round to 2 decimal places. Note that 1m=3.28ft

Answer 1

Set up your multiplication so that you cancel out units that you don't want and introduce those that you do...

(40m/min)(min/60sec)(3.28ft/m)=2.19ft/sec (to nearest one-hundredth)

Answer 2

The answer is 400 meters
