Question 622847
In words:
 tons of snowfall  = ( rate of snow fall ) x ( time of snowfall )
Time = {{{M}}} minutes
( rate of snowfall ) = {{{ T/1 }}} tons/sec
and
( tons/sec ) x ( sec/min) = tons/min 
{{{ ( T/1 )*( 60/1 ) = 60T }}} tons/min
Since the time is in minutes, all the units agree
-----------
 tons of snowfall  = {{{ 60T*M }}}
