Explanation / Answer

4. Price of cents/kg

In dollars/lb = 33 cents/kg x 2.20462 x 100

                   = 0.33 dollar/2.20462 lb

                   = 0.15 dollars/lb

weight of 16 lbs/3) x 16

                                = 8 lbs

Cost of 16 x 0.15

                             = 1.2 dollars

--

5. Distance between two cities = 405 miles

average speed = 72 miles/hr

                         = 72/60

                         = 1.2 miles/min

So times taken = 405 miles/1.2 miles/min

                         = 337.5 min

----

6. automobile gets = 8.15 mi/L

distance = 405 mi

Gasoline consumption = 405 mi/8.15 mi/L

                                     = 49.7 L

In gallons Gasoline consumption = 49.7 L x 0.2642

                                                     = 13.13 gal

Cost of gasoline = 2.34 dollars/gal

So,

cost of travel between two cities = 2.34 dollars/gal x 13.13 gal

                                                    = 30.72 dollars
