A moon is about 210,000 miles from the planet it orbits. Write in scientific notation. If a rocket traveled at 3 x 10^4 miles per hour, how long would it take for it to reach the moon from the planet?

Write the number 210,000 in scientific notation. 210,00 =
It would take the how many hours to reach the moon

• MAT 116 -

210,000 = 2.1*10^5

2.1*10^5 / 3.4*10^4 = 6.17 hours
