Two political activists, Ashley and Jasmine, have a friendly bet to see who can get the most signatures on a petition. So far, Ashley has collected 42 signatures and Jasmine has collected 150 signatures. Ashley is averaging 3 new signatures per minute, while Jasmine is managing to collect an average of 1 signature per minute. Assuming this trend continues, they will have a tie before long. How many signatures will each one have at that point? How long will that take?
