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.
She walked .6 mph because 3/5 x 2= 6/10
1/2 x 2=1
both towns are the same length because they are the same distance away from each other.
0.10(5000) = 500
0.15(10,000) = 1500
total commission on 15,000 = (150 + 500) = 2,000
Answer:
