Calculate the speed of a car that traveled 200 kilometers in 3 hours.

The units (km/h) tell you how to do this! 200km/3h = 66.66666666…. BUT technically you only have ONE significant digit: 3 so 66.666… rounded to ONE digit is 70km/h but that is probably not important in this intro class so V = 66.67 or 67 km/h

66.7km/h

Explanation:

s=d/t

200/3

=66.6666666

round off: 66.7km/h

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

a=d/t

a="triangle"v/t

explanation:

a = acceleration
