Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! rate * time = distance.
rate is 49
distance is 19
formula becomes:
49 * time = 19
divide both sides of this equation by 49 to get:
time = 19 / 49 hours.
that equivalent to .387755102 hours which is equivalent to 23.26530612 minutes which is equivalent to 23 minutes and 15.91836735 seconds.
conversion of hours to hours and minutes and seconds is done in the following manner.
suppose hours is 5.739
subtract the 5 and hold it.
that's your hours.
multiply .739 by 60 to get 44.34
subtract the 44 and hold it.
that's your minutes.
multiply .34 by 60 to get 20.4
that's your seconds.
to convert back, divide the 20.4 by 60 and add it to your minutes of 44 to get 44.34 minutes.
divide that by 60 and add it to your hours of 5 to get 5.739 hours.
in any problem involving rate of travel, the basic equation of:
rate * time = distance
is the formula to use.
