Ground Not For Thy Daily Bread

Ground not for thy daily bread,
Leave me in my scented bed,
Ignore me not, lest I doth wither,
My name I leave you to consider.

Show the answer »

A flower. The soil they grow in is not used for food, like wheat to make bread, but for their smell. A neglected flower will wither.

Mario’s Racing Grandma

Mario is testing out a new car at the racetrack. His grandmother took it for a mile lap and averaged 30mph. How fast does Mario have to drive in the second lap to average 60mph for the two miles?

Show the answer »

90mph is an alluring answer, but it’s impossible. At 90mph the second lap would take 40 seconds. If Grannie’s first lap at 30mph took 2 minutes, traveling 2 miles in 2 minutes and 40 seconds is an average speed of 45mph. Traveling an average speed of 60mph for 2 miles would take 2 minutes and since the grandma’s lap took all of those 2 minutes, even if Mario could break the sound barrier he wouldn’t be able to average 60mph.
