AMP Parsing Error of [100 (ft/sec) 60(sec/min)=6000 (ft/min)]: Invalid function ')60(sec/min)=6000(ft/min)': opening bracket expected at /home/ichudov/project_locations/algebra.com/templates/Algebra/Expression.pm line 70. .
:
there are 5280 feet in 1mi. There are 10 miles
:
10(5280)=52800 feet water has to travel.
:
so we have the velocity at 6000 ft/min and we have total feet.
:
we need to divide total footage by the speed. Distance = rate * time
:
so time = D/r
:
52800/6000 (ft/(ft/min))=8.8minutes to reach town
