Answer: The average speed of the plane in northeast direction is 816 km/hr and that in upward direction is 6.4 km/hr

Explanation:

Average speed is defined as the ratio of total distance traveled to the total time taken.

To calculate the average speed of the runner, we use the equation:

$\text{Average speed}=\frac{\text{Total distance traveled}}{\text{Total time taken}}$ .......(1)

Total distance traveled = 204 km

Total time taken = 15.0 mins = 0.25 hr (Conversion factor: 1 hr = 60 mins)

Putting values in equation 1, we get:

$\text{Average speed of plane}=\frac{204km}{0.25hr}=816km/hr$

Total distance traveled = 1.6 km

Total time taken = 15.0 mins = 0.25 hr

Putting values in equation 1, we get:

$\text{Average speed of plane}=\frac{1.6km}{0.25hr}=6.4km/hr$

Hence, the average speed of the plane in northeast direction is 816 km/hr and that in upward direction is 6.4 km/hr

Answer:

230 m/s northeast, 1.8 m/s up

Explanation:

204 kilometres = 204000 metres

15.0 minutes = 900 seconds

Velocity = Distance / Time

= 204000 / 900

= 230 m/s northeast (to 2 sf.)

1.6km = 1600 metres

Velocity = 1600 / 900

= 1.8 m/s up (to 2 sf.)
