39 ft/min is how many yd/s
Arlecino [84]
0.0181 yd/s. To solve this problem you use dimensional analysis. You convert the feet and minutes to yards and seconds by using this process. The units of feet and minutes cancel out, so you are left with yards per second. You should get 0.0180555555 when you multiply and divide everything, but you can just round it to 0.0181 or whatever place your teacher wants.

26 inches is how many yards
AlekseyPX

1 yard = 36 inches

The fraction  (1 yard / 36 inches) has a numerator and denominator
that are equal.  So the fraction is equal to ' 1 ', and we can multiply
(26 inches) by it without changing any value.  That'll change the units
of the '26 inches' to 'yards', which is exactly what we need.

(26 inches) x (1 yard/36 inches) = (26/36) yard

                                                 That's  13/18 yard, or  0.7222... yard.
