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 = $Speed \times Time = 52\times9 = 468 miles.$

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 = $\frac{Distance}{Time}=\frac{468}{6}= 78 \ mph$

Hence Speed of car is 78 mph which travels the distance in 6 seconds.
