I think it would be the last one from my calculations im not positive but its what makes sense.
Answer:
The rate of change of the distance between the cars at that instant is 5.46 meters per second
Step-by-step explanation:
Speed of first car = 7 m/s
Speed of second car = 3 m/s
At instant, distance of first car from intersection = 5 meters
distance of second car from intersection = 12 meters
Therefore, we have
Distance between both cars at intant = √(12² + 5²) = 13 m
Rate of cahnge of distance is given by;
2ddd/dt = d(x² + y²)/dt = 2xdx/dt + 2ydy/dt
= 26dd/dt = 2×5×7 + 2×12×3 = 142
dd/dt = 142/26 = 5.46 m/s.
That is the rate of change of the distance between the cars at that instant = 5.46 meters per second.
Answer:
circle P has a circumference of 800mm which is equal to 80cm
circle Q is 200cm
circle R is 4m which is equal to 400cm
You will get the sum of the distances by placing the figures under one measurement that is meters
And so add the figures in cm(200+400+80) and get 680
Then convert this to meters and get 6.8m
Hence your answer is C
