A jogger is jogging to the park a distance of 12 miles She then jogs home at the same speed but along a different route This return trip is 18 miles and her time is one hour long what is her speed?

Total distance = 12 + 18 = 30 miles

Total time = 1 hour

Speed = distance/time = 30 miles per hour.

Comment: Wow! Ever heard of the old Olympic 4-minute-mile record? Multiply by 15 and that old Olympic barrier would translate to an hour for running 15 miles (15 miles per hour). In the question above, the "jogger" is twice as fast, sustained for a whole hour! The hypothetical jogger in the question definitely can not be human. (If you actually did that, please contact me, and as your trainer I'll make you very rich and world famous!)
