Answer:
Oerhaps 17.3333 miles, see assumption below
Explanation:
There are no units for 52. 52 m/sec? 52 feet/min?, 52 mph?
Once we have the units for the 52, convert the 20 minutes to the same unit as in the speed unit, hours in this case. I'll assume miles/hour for the speed here. So convert 20 minutes into hours: (1 hr/60min)*(20 minutes) = (1/3) hour.
Now multiply by the 52 mph:
(52 miles/hr)*(1/3 hour) = (52/3) miles or 17.33 miles
