The answer will depend on where in the world, and at what level (school performance or world-class theatre).
45mls/hour
The average rainfall rate in inches per hour in our region is 0.25 inches per hour.
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.
His rate is 4 miles per hour.
15 dollars/hour is the unit rate
21 miles per hour is equal to 36960 yards per hour. Since this is the rate per hour, we must divide that by 60 for minutes to leave 616 yards per minute.
Use this formula to convert miles per second to miles per hour:mps x 3,600 = mph
148 kilometers per hour is 91.96 miles per hour.
The rate of evaporation observed in the experiment was 0.5 mL per hour.
411.68 kilometers per hour is 255.80609232256 miles per hour the conversion rate is 1 kilometer an hour = .621371192 miles per hour
0.6 Ounces per hour.
about 15 gallons per hour
