Walking with 4/5 of my usual speed, I arrive at the bus stop 8 minutes later than normal. How many minutes does it take to walk to the bus stop at my usual speed?
Choose the correct choice from the following options:
A) 20
B) 24
C) 28
D) 32
E) 36
Let t = usual time = distance / usual speed   t + 8 = distance / (4* usual speed/5) = (5 * distance) / (4 * usual speed) = 5t/4   t = 32   The answer is 32.
