Question

An object is moving at a speed of 49 yards per week. Express this speed in feet per minute. Round your answer to the nearest hundredth.

Answer 1

0.01 ft/min

Explanation:

Use dimensional analysis to convert the units:

`(49\ yards)/(1\ week) * (3\ feet)/(1\ yard) * (1\ week)/(7\ days) * (1\ day)/(24\ hrs) * (1\ hr)/(60\ min) = 0.01458\ ft/min`

Rounded to the nearest hundredth, the speed is 0.01 ft/min.
