Answer: t = 340+22-10

Step-by-step explanation:

Hi, to answer this question we have to analyze each runner:

Norma takes 340 seconds to run the course.

Norma's time = 340

Jeremy takes 22 seconds longer to run a particular course than Norma. Since he takes seconds longer, we have to add that amount to Norma's time:

Jeremy's time = Norma's time + 22 = 340+22

Eleanor is a faster runner than Jeremy by more than 10 seconds. Since she is faster, we have to subtract 10 seconds to Jeremy's time to obtain Eleanor's time (t)

t = Jeremy's time - 10

t = 340+22-10 (seconds)
