Two cars drive on the same highway in the same direction . The graphs show the distance , d, of each one as a function of time , t. Which car drives faster ? Explain how you know.

Car B

Step-by-step explanation:

If we take a random time value, and just draw a vertical line, we see that in the same amount of time, car B has traveled more distance (it's d-value is larger, it's above A).

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
