Calculate the speed.

1. If a car travels 800m in 30 seconds how fast is it going?

s = 26.7 m/s

Explanation:

Given data:

Distance travel = 800 m

Time taken = 30 sec

Speed of car = ?

Solution:

Formula:

S = d/t

s = speed

d = distance

t = time

by putting values.

s = 800 m/ 30 s

s = 26.7 m/s

it should be all of them because it asks if you included all of those in your answer

explanation:

1.solid

2.carbon dioxide

3.helium
