The freight demand on a 1150 km (Lm) long route section is projected to be efx105 tons/year (Tm). On this section, a single ton load is carried out to an average distance of bi0 m (m). The load is planned to be carried by rolling stock having a capacity of bhi ton/rolling stock (am). If the maximum daily freight amount / average daily freight amount is 1 (k1), the wagon usage coefficient is 0,b (k2) and the rolling stock usage coefficient is 0,75 (k3), find the number of rolling stock to be operated each day
