In 1.50 short tons there are how many nanograms? Report your answer to 3 s.f. using scientific notation as described in #10 & #11. Do not include units in your answer. Potentially useful conversion factors: 1 L = 1000 mL; 1 L = 1.057 quarts; 1 gallon = 4 quarts; 1 mile = 5280 feet; 1 foot = 12 inches; 1 inch = 2.54 cm; 1 meter = 100 cm; 1 kilometer = 1000 m; 1 g = 0.03527 oz; 1 lb = 16 oz; 1 short ton = 2000 lbs A car averages 45.00 miles per gallon of gas. How many kilometers can it travel on 10.0 liters of fuel? Report your answer to 3 s.f. using scientific notation as described in #10 & #11. Do not include units in your answer. 1 L = 1000 mL: 1 L = 1.057 quarts; 1 gallon = 4 quarts; 1 mile = 5280 feet; 1 foot = 12 inches; 1 inch = 2.54 cm; 1 meter = 100 cm; 1 kilometer = 1000 m; 1 g = 0.03527 oz; 1 lb = 16 oz; 1 short ton = 2000 lbs

Solution

1 short ton = 2000 lbs

                     = 2000 x 16 oz

                     = (2000 x 16)/0.03527 g

                     =( (2000 x 16)/0.03527)x10⁹ ng

Then 1.5 short tons = 1.5x( (2000 x 16)/0.03527)x10⁹ ng

                                    =1.36x10¹⁵ ng

2. 1 miles = 5280 feet

                     = 5280 x 12 inches

                     = 5280 x 12 x 2.54 cm

                     = (5280 x 12 x 2.54)/100 meters

                     = (5280 x 12 x 2.54)/100 x 1000 kilometres

And        1 gallon = 4 quarts

                                = 4/1.057 liters

Then average of car =miles / liters

That is 45 = miles / 2.6425 (10 liters = 2.6425)

                45 x 2.6425 = miles

                118.9125 = miles              

Then 118.9125 miles = 118.9125 x (5280 x 12 x 2.54)/100 x 1000 kilometers

                                        =19137111.84/100 x 1000 kilometers

                                        =191.37111kilometers
