A car starts at mile marker 145 on a highway and drives at 55 mi/hrmi/hr in the direction of decreasing marker numbers. What mile marker will the car reach after 2 hours

135 mile marker will the car reach after 2 hours.

Explanation:

Speed of the car = 55 mile/hour

Distance covered in 2 hours = d

The direction of the car is in decreasing marker numbers which mienas that car had started from end where 145 mile marker was present.

So, the marker appearing after travelling 2 hours will be:

145 - 110 = 135

135 mile marker will the car reach after 2 hours.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
