Question

An electron travels 1.92 m in 4.47 × 10^−8 s.
How fast is it traveling?
Answer in units of m/s

Answer 1

You've got the answer right in front of you! "m/s", which means meters per second. Divide the speed by the time and you'll get your answer.

Answer 2

Remember to check that the units you have are part of the final units in the answer. In this case you have meters AND seconds, and you need meters/seconds (meters OVER seconds) which means displacement (m) per ONE unit of time (s) . Just proceed as EbnorEqvine said.

Answer 3

How do you set it up in a caculator?

Answer 4

Type: \[1.92\div4.47\times10^{-8}\]

Answer 5

"Divide the speed by the time and you'll get your answer." I think Ebnor ment "divide the distance by time". I'm saying this just to avoid confusion.

Answer 6

4.50*10^7 m/s
