The car was towed for 48 miles.
Step-by-step explanation:
Given,
Amount charges by Acme towing = $30
Per mile charges = $3
Total charged = $174
Let, x be the number of miles.
Towing charges + Per mile charges*number of miles = Total charged
30+3x=174
Subtracting 30 from both sides
Dividing both sides by 3
The car was towed for 48 miles.
