Yes, although it does not specify 15 WHAT per hour. [Run] 15 miles per hour or [make] 15 dollars per hour or [manufacture] 15 widgets an hour. To that extent, it is not a unit rate.
Yes, it is.

It would take you 12 Hours. Speed = Distance over time. So 180 over (divided by) 15 = 12 Hope i helped. :)
12 over 15.
15 / 50 = 0.3 feet per hour
