Jade normally leaves work at 5: 00 pm, but she is leaving work 10 minutes late today. she decides to make up time by taking the toll road instead of side streets. she can travel two times faster by taking the toll road. create an equation in terms of x to represent the number of minutes after 5: 00 pm she arrives home from work if she leaves late. let x represent the number of minutes her normal commute takes when she leaves on time.

y equals one half times x minus ten

y = 2x − 10

y = 2x + 10

y equals one half times x plus ten
