Two runners start at the same point but facing in the opposite direction. Each runner then runs
straight for 3 miles, takes a right turn, and runs straight for another 4 miles.
What is the distance in miles between the two runners at that point?
: 10 miles.
: See the image below:
For those familiar with common right angle triangles, if the short sides measure 3 and 4, the
longest side (the hypoteneuse) measures 5. Or, we can calculate the hyptoneuse using Pythagoras'
3² + 4² = x²
x = 5 miles
Each runner is 5 miles from the starting point so the distance between the two runners is 10 miles.
Do you have a suggestion
for this puzzle (e.g. something that should
be mentioned/clarified in the question or solution, bug, typo, etc.)?
