Train a departs station one traveling at 75 mph. train n departs station two 30 minutes later traveling at 45 mph. the stations are 300 miles apart. the equation below gives the distance between the trains, d, in miles as a function of, t, the time after train b departs. d=|262.5-120t| for which two values of t will d=50? round to the nearest tenth. a)1.8 and 2.6 b)0.2 and 0.3 c)-17.8 and 26.0 d)-1.8 and 1.8

Acompany manufactures large valves, packed in boxes. a shipment consists of 1500 valves packed in 75 boxes. each box has the outer dimensions 1.2 x 0.8 x 1.6 m and the inner dimensions 1.19 x 0.79 x 1.59 m. the boxes are loaded on a vehicle (truck + trailer). the available capacity in the vehicle combination is 140 m3. each valve has a volume of 0.06 m3. - calculate the load factor on the box level (%). - calculate the load factor on the vehicle level (%). - calculate the overall load factor (%).
