The Hubble constant is usually measured in units of km/s⋅Mpc, but in order to use the Hubble constant to calculate the Hubble time, it must be converted into units of s−1. What is 50.0 km/s⋅Mpc in units of s−1? Give your answer in scientific notation to two decimal places.
What is 65 km/s/Mpc in units of s−1? Give your answer in scientific notation to two decimal places.
Messier 60 is a galaxy in the constellation Virgo. It has a -factor of 0.00373. How far away is Messier 60? Use a value of 74.0 km/s⋅Mpc for the Hubble constant. Give your answer to one decimal place.
