The answer would be B. 1 because by using the pythagorean theorem ((a^2)+(b^2)=(c^2)) on this right triangle, (a^2)=((sqrt(3))^2)=3, (b^2)=?(let's use x), and (c^2)=(2^2)=4. So, (c^2)-(a^2)=(b^2). 4-3=1 and (sqrt(1))=1.

Answer:
Speed of car is 78 mph which travels the distance in 6 seconds.
Step-by-step explanation:
Given:
Speed of the car R = 52 mph
Time t = 9 seconds
We need to find the speed of a car that travels the given distance in 6 seconds.
Now first we will find the distance traveled by the car in 9 seconds.
Distance can be calculated by multiplying speed and time.
Distance = 
Hence Total distance travel by car is 468 miles.
Now we will find the speed of a car that travels the given distance in 6 seconds.
Speed can be calculate by dividing Distance by time.
Hence;
Speed = 
Hence Speed of car is 78 mph which travels the distance in 6 seconds.
