#### Answer

Beth arrives at 3:40 pm, while Alan arrives at 4 pm.

#### Work Step by Step

(distance)=(rate x time) (time)=(distance$\div$rate) For Alan, (time)=(400$\div$50)= 8 hours. 8 a.m + 8 hours = 4 P.M. For Beth, (time)=(400$\div$60) = (20$\div$3) = 6 hours and 40 minutes. 9 a.m + 6 Hours and 40 minutes = 3:40 P.M. Beth arrives first.
