Question

In 1959, Russia sent the Luna 1 spacecraft towards the moon. It made 3.8x10 to the 5th power kilometer trip to the moon in 2.16x10 to the 3rd minutes. Write and expression for the speed of Luna 1 in kilometers/minute. Represent this expression as a quotient of two numbers expressed in scientific notation

Answer 1

The distance between Earth and the moon is 3.8 x 10^3 Kilometers. The time taken to travel this distance was 2.1 x 10^3 Minutes.

The formula to calculate speed is Speed = distance/time.

So, the speed of Luna I was 3.6 x 10^3 / 2.1 x 10^3 Kilometers/Mintues.
