Answer: 4 hours
Explanation:
It takes the kayak 1 minute to travel 35 meters.
Divide the total (8400m) by the amount of meters per minute (35m)
Now convert into hours. (Remember that 1h has 60min)
From the conversion of units:
1 cm^3 is equivalent to 1 mL
1 L is equivalent to 1000 mL
therefore,
to convert from liter to cm^3, we simply multiply by 1000.
Note that the multiplication will be done in the denominator.
Based on this:
density = (0.625 g/l) x (1g/1000 cm^3) = <span> 0.000625 g/cm^3
= 6.25 x 10^-4 g/cm^3</span>
