Answer:
2.4 days
Step-by-step explanation:
Time working together,t ,is
1/t = 1/a+ 1/b where a and b is the times working alone
1/t = 1/4 + 1/6
Multiply each side by 12t to clear the fractions
12t( 1/t )= 12t(1/4 + 1/6)
12 = 3t+2t
12 = 5t
Divide by 5
12/5 = 5t/5
2 2/5 =t

1 degree is
radians. So 14 degrees is
rad.
Easy way to remember this: one complete revolution in a circle is 360 degrees. But it's also
radians. So the conversion rate is

i.e. for every
radians there are 180º.
