Atourist being chased by an angry bear is running in a straight line toward his car at a speed of 4.2 m/s. the car is a distance d away. the bear is 30 m behind the tourist and running at 6.0 m/s. the tourist reaches the car safely. what is the maximum possible value for d?

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
