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.

They will have same amount in 45 weeks.
Step-by-step explanation:
Given,
Starting amount of Nancy = $425
Per week saving = $25
Let,
x represent the number of weeks.
N(x) = 25x+425
Starting amount of Seamus = $875
Per week saving = $15
S(x) = 15x+875
For same amount;
N(x) = S(x)
Dividing both sides by 10
They will have same amount in 45 weeks.
