Which rate is the greatest 800 miles per 16 hours 1500 miles per 50 hours 600 miles per 15 hours or 900 miles per 20 hours?
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.
Is this a unit rate 15 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.
