gistfile1.txt

# Given:
# 5 songs of the following lengths in seconds
# 223,215,378,324,254

# Goals:
# Assign the length set to variables
# Calculate the Total Length of the Playlists
# Express the Length in Minutes
# Average Song Length in Minutes

lengths = [223, 215, 378, 324, 254]

total = lengths.inject(:+)
totalmin = total / 60.0

avglength = totalmin / lengths.size

puts "Total length of songs = #{total} secs"
puts "Total in min = #{totalmin}"
puts "Avg song length (min) = #{avglength}"
