Question

A weather reporter in your area said that the speed of sound in air today is about one thousand one hundred feet per second. What is that speed in scientific notation?

Answer 1

Answer:

The speed in scientific notation is $(1.1)(10^{3})$ feet per second.

Step-by-step explanation:

1. You have the following speed: One thousand one houndred feet per second.

2. You must convert from words to number. This is:

1,100 feet per second

3. To express this quantity in scientific notation, you can move the decimal point three places to the left, and write it as: 1.1 by $10^{3}$ (or 1,000) as following:

$1,100=(1.1)(10^{3})$
