Question

Alex had an exercise routine he used to prepare for his soccer games. For each exercise set he would run for 5 minutes and then cool down for 1 minute. He wrote this equation to represent the total time spend on one exercise set.
t = 5 + 1



Which equation would represent the total time Alex spent on 5 exercise sets?


A.
t = 5 + (5 + 1)


B.
t = (5 • 5) + 1


C.
t = 5 + (5 • 1)


D.
t = 5 • (5 + 1)

Answer 1

The answer would be D because you are multiplying the amount of sets by the amount of minutes he runs and the amount of minutes he takes a break for.
