One day I decided to walk all the way from Bangalore to
Tumkur. I started exactly at noon. And someone I know in Tumkur decided to walk
all the way to Bangalore from Tumkur and she started exactly at 2 p.m. on the
same day.
We met on the
Bangalore- Tumkur road at five past four, and we both reached our destination
at exactly the same time. At what time did we both arrive?
Answer:
The key
to the solution is that with a little bit of pencil work, it will be found,
while I can walk 5 miles, my friend who started from Tumkur can walk 7 miles.
Let’s assume the distance between Bangalore and Tumkur is 24 miles, then the
point of meeting would be 14 miles from Bangalore , and therefore , I walked 3
³⁄₇ miles per hour while my friend walked 4 ⁴⁄₅ miles per hour, and we both
arrived exactly at 7 P. M.
