The technique which is the most useful for measuring the distance to a galaxy located 10 million light-years away is Cepheids
A Cepheid variable is a particular kind of star that pulses radially, varying in diameter and temperature while causing changes in brightness with a clearly discernible steady time and amplitude.
A light-year is defined as the total amount of distance covered by light in a year. It is usually a unit to measure very large distances which usually concerns the Outerspace
A galaxy is a system made up of stars, stellar debris, interstellar gas, dust, and other matter that is gravitationally bound. The name "galaxy" is derived from the Greek word "galaxies," which is an allusion to the Milky Way and literally means "milky."

Find this answer on safari and if you can’t reply to me and i’ll help
Answer:
applying 1st eq of motion vf=vi+at here we have to find a=vf-vi/t , a= 1-1/5 , a=0/5 then we got a=0 here(vf value 3.6km/h is converted in standard unit 3.6×1000/3600 so we get vf=1m/s²
