First we calculate how far did Maria go for 2 hours.
#v_1=s_1/t_1#
#30 mph=s_1/[2] #
#s_1= 60# meters
Then we calculate how far did Ming go for 2 hours.
#v_2=s_2/t_2#
#32 mph=s_2/[2] #
#s_2= 64# meters

The total distance [#s_t#] between them in 2 hours is...
#s_t=s_1 +s_2#
#s_t=124# meters
Maria and Ming are 124 meters far from each other.
