7.5 degrees per hour
The answer depends on whether you mean 15 degrees on a clock face (0.5 hours) or 15 degrees of longitude (1 hour).

Convert them all to the same per x hours and then compare them. You can either convert them all to unit rates (x = 1) or some other rate (eg lcm of 16, 50, 15 and 20). I'll use unit rates: 800 miles per 16 hours = 800 ÷ 16 miles per 16 × 16 hours = 50 mph 1500 miles per 50 hours = 1500 ÷ 50 miles per 50 ÷ 50 hours = 30 mph 600 miles per 15 hours = 600 ÷ 15 miles per 15 ÷ 15 hours = 40 mph 900 miles per 20 hours = 900 ÷ 20 miles per 20 ÷ 20 hours = 45 mph 50 mph is the greatest unit rate → 800 miles per 16 hours is the greatest rate. --------------- The rates can be ordered: 50 > 45 > 40 > 30 → 800 miles per 16 hours > 900 miles per 20 hours > 600 miles per 15 hours > 1500 miles per 50 hours.
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.
7.5 degrees per hour
15 / 50 = 0.3 feet per hour
A car has traveled 195 miles in 3 hours. Find the unit rate.
15 dollars/hour is the unit rate
The answer depends on whether you mean 15 degrees on a clock face (0.5 hours) or 15 degrees of longitude (1 hour).
Since Earth has ROUGHLY one full rotation (360 degrees) every day, that is equivalent to 360 degrees / 24 = 15 degrees per hour.
15. There are 24 hours; a full rotation is 360, so 360 divided by 24 is 15.The earth spins approximately 360 degrees in twenty four hours (one day).The earth spins 15 degrees in one hour. _____________ The above is correct in a general sense, but this is a little more complex than meets the eye. The earth spins very close to what might be called 15 'synodic' degrees in one hour, if you are dealing with coordinate degrees of longitude relative to the sun. But since the earth spins more than 360 sidereal (or absolute) degrees in 24 hours, the number of sidereal degrees per hour must be slightly greater than 15, since slightly less time (sidereal day) amounts to 360 absolute degrees. The sidereal day is about 23.93447232 hours. The earth spins 360 absolute degrees in this period of time. This yields roughly 15.041 degrees of sidereal spin per hour.15 degrees
It rotated 15 degrees, because 360 divided by 24 is 15, and 15 times 3 is 45.

The Earth rotates 360 degrees in 24 hours, which means it rotates 15 degrees per hour (360 degrees / 24 hours = 15 degrees/hour). Therefore, in 2 hours, the Earth will rotate 30 degrees (15 degrees/hour x 2 hours = 30 degrees).
