The cost for the two hundred gallons is 0.91 x 200 = 182 dollars.

Thus, the number of hours to consume 200 gallons of fuel is 182/0.7 = 260.

1 gallon costs $0.91;
Consumed at a rate of $0.70 worth of fuel per hour.

So, in 1 hour 0.7/0.91 gallons are consumed. Therefore, 200 gallons will be consumed in 200/(0.7/0.91) = 260 hours.

Answer: C.

\(\frac{200}{(\frac{0.7}{0.91})} = 200*\frac{10}{7}*\frac{91}{100} = 20*13=260\).
