Question 771147: use the distance formula d = rt to find out how far I can go in a certain amount of time when traveling at a certain rate. Let's solve for r (get r alone) on the above formula. Then, let's find out what our rate was if we traveled 100 miles in 1 hour and 36 minutes. Hint: change 36 minutes to hours.
Can you please show me the steps to follow when working this sort of problem?

Always there are three aspects of solving these type of problems.
You should remember the letters FCC
F-Formula you are going to use
C-Conversion to right units
and C- calculation the last part
Formula = d=rt
we have to find r
r= d/t
time should be in hours because speed is in mph
36 minutes = 36 /60 = 3/5 hours
1 3/5= 8/5 hours
r = 100 / (8/5)
x= 100 * 5/8
r= 125/2 = 62.5 mph
