50 mph = 50 miles in 60 minutes = 5 miles in 6 minutes divide both by 5 so 5/5 miles = 1 mile in 6/5 minutes = 360/5 seconds = 72 seconds 548 x 72 = 39,456 seconds = 39,456/60 minutes = 657.6 = 657.6/60 hours = 10.96 hours Answer: 10 hours 57 minutes 36 seconds. Alternatively, speed = distance/time so time =distance /speed = 548/50 hours = 10.96 hours, or 10 hours, 57 minutes and 36 seconds.
4.5 mph i think isnt it speed = distance over time so 300 divided by 72 = 4.5 approx
259,200 seconds = 72 hours
259200 seconds = 259200/3600 hours = 72 hours
3600 seconds in an hour 72 hours in 3 days x 3600 = 259200
1 mile/50 sec * 3600 sec/hr = 72 mph
50 seconds

50 miles = 60 minutes 5 miles = 6 minutes = 360 seconds 1 mile = 72 seconds 3 miles = 216 seconds or 3600/50 x 3 = 216 Answer: 3 minutes 36 seconds
The distance between them is closing at (20 + 30) = 50 mph.It will close 1 mile after (1/50th) of an hour = 72 seconds

50 miles = 60 minutes 50/50 miles = 60/50 minutes 1 mile = 6/5 minutes 12 miles = 12 x 6/5 minutes 12 x 6/5 = 72/5 = 144/10 = 14.4 60 x 0.4 = 24 or 5 miles = 6 minutes = 360 seconds 1 mile = 360/5 = 72 seconds 12 miles = 12 x 72 = 864 seconds 60 x 14 = 840 = 864 - 24 Answer: 14 minutes 24 seconds
