Answer:
The answer is the 59 gallons per 13 minutes.
Step-by-step explanation:
the first tank is filling at a rate of 175 gallons per hour because 60/12 is 5 and 35*5 is 175. the second tank is filling at a rate of 272.3 gallons per hour because 60/13 is 4.6 and 59*4.6 is 272.3
0.75m + 5 = 0.5m + 9
0.75m - 0.5m = 9 - 5
0.25m = 4
m = 4 / 0.25
m = 16 <=== at 16 miles, the companies will charge the same amount
