joe and marjorie are both competing in a half marathon. joe runs the first 8 miles of the race in 1 hour and marjorie runs the first 8 miles of the race in 52 minutes. if they maintain these individual rates, how many minutes faster will marjorie's half marathon finish time be than joe's? (a half marathon is a 13 mile race.)

13 minutes

Step-by-step explanation:

∵ Joe runs 8 miles in the time = 1 hour or 60 minutes

∴ Joe runs 1 mile in the time = minutes

∴ Joe runs 13 miles in the time = minutes

                                                   = 97.5 minutes

∵ Marjorie runs 8 miles in the time = 52 minutes

∴ Marjorie runs 1 miles in the time =

∴ Marjorie runs 8 miles in the time =

                                                         = 84.5 minutes

Therefore, times taken less by Marjorie to complete the marathon = 97.5 - 84.5 = 13 minutes.

8

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
