Rosy has been jogging for 3 weeks. In the first week She jogged 3 days each for 4/6 of an hour. During week 2 she jogged for 3/4 of an hour on 2 days. In week 3 she jogged 4 days each for 3/5 of an hour . WRITE one expression that would show the total time she spent jogging in 3 weeks , solve
3 * (4/6) + 2 * (3/4) + 4 * (3/5)
= 2 + 3/2 + 12/5
= 20/10 + 15/10 + 24/10
59/10 = 5.9 hours = 5 hours 54 minutes
To find the total time Rosy spent jogging in 3 weeks, we need to add up the time she spent jogging each week.
In week 1, she jogged 3 days, each for 4/6 of an hour. So, the total time spent in week 1 is:
3 days * (4/6 hour/day) = 12/6 = 2 hours
In week 2, she jogged for 3/4 of an hour on 2 days. So, the total time spent in week 2 is:
2 days * (3/4 hour/day) = 6/4 = 1.5 hours
In week 3, she jogged 4 days, each for 3/5 of an hour. So, the total time spent in week 3 is:
4 days * (3/5 hour/day) = 12/5 = 2.4 hours
To calculate the total time spent jogging in 3 weeks, we need to add up the time from each week:
2 hours (week 1) + 1.5 hours (week 2) + 2.4 hours (week 3) = 5.9 hours
So, the expression that shows the total time Rosy spent jogging in 3 weeks is:
2 + 3/5 + 1.5 = 5.9 hours
