What is 60 ft/s = mi/min round to the nearest tent if necessary

60ft/s -- 60s in a min, multiply by 60
3600ft/min -- 1 mile is 5280 feet, divide by 5280
Approximately 0.681818

We know, 1 mi/min = 88 ft/s
So, 1 ft/s = 1/88 mi/min

Now, 60 ft/s = 1/88 * 60 = 0.681 
After rounding-off to the nearest tenth, it would be: 0.7

In short, Your Answer would be 0.7 mi/min

Hope this helps!
