The braking distance, D, of a car is directly proportional to the square of its speed, v. When d=5, v=10 Find d when v=70

Step-by-step explanation:

d is directly proportional to the square of a speed v

d = av²

5 = a•10²

5 = 100a

a = 0.05

d = 0.05v²

d = 0.05•70²

d = 0.05•4900

d = 245

probability for j is 1/4

while

a is 1/6

a: inscribed angles
