What Are Some Scientific Notation Word Problem Examples?

Scientific notation word problems ask the student to perform operations with two or more large numbers. For example, if light travels at 3 x 10^8 meters per second, how far will a beam of light travel in one day?

Other scientific notation word problems include:

The speed of light is 3 x 10^8 meters/second. If the sun is 1.5x 10^11 meters from earth, how many seconds does it take light to reach the earth?

The half-life of Uranium 234 is 2.5 x 10^5 years and the half-life of Plutonium is 8.0 x 10^7 years. How many times greater is the half-life of Plutonium than Uranium 234?
