Answer:

4times

Explanation:

The right-hand side of the equation \frac{v^{2} }{b} computes braking distance by applying a braking coefficient factor (b) to the square of the car's velocity.

the brake coefficient is 170 and the velocity of the car is V.

At 20mph = 20^2 divides 170 = 2.3594

At 40mph = 40^2 divides 170 = 9.4117

Hence it is 4 times greater of 20mph
