Answer:
Step-by-step explanation:

Convert 1 and 1/2 to eights to make it easier to subtract. 1 4/8 add 1 to 4/8
12/8 then subtract that by 7/8 straight across the numerator. That then equals 5/8
We'll represent the distance as d and the time as t.
d= 3(t+7) because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5) because Gilda is 5 minutes early at 4 mph
d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.
