Question from Joyce, a student: Jake can travel 37 miles in 3 seconds,please calculate jake's rate of speed.(round to 2 decimal places) |
Hi Joyce,
Wow! Jake's car is really fast. Many times faster than the world land speed record.
You didn't say what units you wanted. He goes 37 miles in 3 seconds so he goes one-third of 37 miles in one second. That is his speed is
\[\frac13 \times 37 \mbox{ miles per second}.\]
Divide 37 by 3 and round the result to 2 decimal places.
