 HELPPPPP!!!!

Answer 1

Answer:

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 = $\frac{60}{8}$ minutes

∴ Joe runs 13 miles in the time = $\frac{60\times 13}{8}$ minutes

                                                   = 97.5 minutes

∵ Marjorie runs 8 miles in the time = 52 minutes

∴ Marjorie runs 1 miles in the time = $\frac{52}{8}$

∴ Marjorie runs 8 miles in the time = $\frac{52\times 13}{8}$

                                                         = 84.5 minutes

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