<PRE><B>Question 819915</B>
we need to find the total time and distance
we know it took her 6 hours and she went 75+195=270
mph= 270/6=45 mph average speed from san antonio to dallas
but we want to know from san antonio to austin
6-2=4 hours actual traveling time

(r+10)*t=75,
r*(4-t)=195
r = 65,   t = 1
r+10=75 mph from san antonio to austin
1+2+3=6
she took three hours at 65 mph to get from austin to dallas.
3*65=195
