A range of motion in degrees is considered ratio data. This is because it has a true zero point (0 degrees indicates no movement) and allows for meaningful comparisons and calculations, such as ratios (e.g., one range of motion can be twice as large as another). Additionally, both the differences and the relative magnitudes between measurements can be interpreted meaningfully.
Interval scales have measurements which are in equal distance from each other. For example, the difference between 70 degrees and 80 degrees is 10, which is the same as the difference between 40 degrees and 50 degrees. Ratio scales are similar to interval scales but include an absolute 0 measurement, which signifies the point when the characteristic being measured vanishes. For example, income (measured in dollars) at 0 means no income at all. Basically, interval and ratio scales are the same, but ratio scales must be able to be measured at a zero starting point.

Time is ratio data because it has a true, meaningful data. You can say that at time 20 seconds, it is twice the amount of time than 10 seconds. Interval data doesn't have a true zero e.g. degrees celcius. Although you can say 60 degrees is hotter than 30 degrees you can't say that it is twice as hot.
It is ratio.
