Jessie hops for 1 minute then rests for 15 seconds.she repeats this pattern for several minutes. Write a pattern showing the number of seconds when jessie switches from one activity to the next. After how many seconds will she start resting for the fourth time

Answer 1

She will start resting for the fourth time in 60 seconds

Answer 2

60secs 15secs 60secs 15secs 60secs 15secs 60secs 15secs
  hop        rest     hop        rest      hop       rest    hop        rest

So now we add 60+15+60+15+60+15+60 = 285

Jessie will have been hopping and resting for 285 seconds before Jessie starts resting the 4th time.
