“The breaking distance is directly proportional to the square of its speed”
Using your variables, this means: d = k•b^2
k here is some unknown (and for this question irrelevant) number.
Now if b (the speed) is increased by 200%, then your new speed is b+2b = 3b. The 2b is the 200% increase.
Throw 3b into the first equation we have the new d as:
d = k • (3b)^2
Simplifying this, you have d = k•9b or d=9kb
This means the new braking distance is 9 times the original braking distance.
the answer to your question is C
Answer:4
Step-by-step explanation:
finding the product of 2 numbers means that you have to multiply those numbers
when multiplying fractions , numerators are multiplied by numerators and denominators by denominators
therefore product of 3/8 and 16 is 6
next we have to find 2/3 of 6
'of' operator means multiplication
answer is 4
