Question 914244
In words:
( miles / hour ) x ( hours / min ) x ( min / sec ) = miles /sec
-----------------------
Now convert ( miles / sec ) to ( feet / sec )
-----------------------
( miles / sec ) x ( feet / mile ) = feet / sec
---------------------------------------
Finally, 
( feet ) / ( feet/sec ) = seconds
-----------------------------
Filling in the numbers:
{{{ 150*( 1/60 )*( 1/60 ) = .041667 }}}
and
{{{ .041667*( 5280/1 ) = 220.00176 }}}
and
{{{ 300 / 220.00176 = 1.3636 }}}
It would take about 1.364 sec
