Question

Eleanor is a faster runner than Jeremy by more than 10 seconds. Jeremy takes 22 seconds longer to run a particular course than Norma. Norma takes 340 seconds to run the course. If the time it take Eleanor to run the course is written as t, what is an expression for t?

Answer 1

Answer: t = 340+22-10

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)
