1.how many gallons in 5.855 times 10^8mL?

2. Convert 55.5 miles/hours to meters/sec?

please use the factor labeling method step by step to show me the answer

thank you

1 US gallon = 3.785 litres
1 litre =  1 / 3.785 gallon
5.855 x 10^8 mL = 5.855 x 10^5 L = 5.855 x 10^5 x 1 / 3.785 gallon

= 1.546 x 10^5 gallons.

1.   3785.4118ml=1gallon so 5.855times10^8ml=  5.855times10^8/3785.4118 gallons                                    2.   1mile=1609.344m therefore 55.5mile/hr =1609.344x55.5/3600m/sec

2. Convert 55.5 miles/hours to meters/sec?

1 miles = 1 609.344 meters
I hour = 60 x60 = 3600 secs.
55.5 miles/hours = 55.5 x 1 609.344 metres/ 1 x 3600 secs
                      = 24.81 metres / sec
