If you had a time machine, when in history--or into the future--would you go?
It’s fun to think about what we might do with time travel, but even more fun to think about HOW we might time travel, because the how of this fantastical adventure would inevitably require scientific and mathematical thinking. Even when that scientific thinking is more science-fiction than science-fact, the math will always be firmly rooted in reality. So get ready to practice your elementary math skills, including multiplication, division, and rounding, as we figure out how we might travel through time in this week’s fun word problem challenge!
Challenge: A time machine requires 1.21 gigawatts of electricity to travel through time. A car battery generates about 12,000 watts to start a car. How many car batteries would be needed to send the time machine through time?
(Hint: A gigawatt is a billion watts.)
