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.)

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:
[tex]\text{Average speed}=\frac{\text{Total distance traveled}}{\text{Total time taken}}[/tex] .......(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:
[tex]\text{Average speed of plane}=\frac{204km}{0.25hr}=816km/hr[/tex]
Total distance traveled = 1.6 km
Total time taken = 15.0 mins = 0.25 hr
Putting values in equation 1, we get:
[tex]\text{Average speed of plane}=\frac{1.6km}{0.25hr}=6.4km/hr[/tex]
Hence, the average speed of the plane in northeast direction is 816 km/hr and that in upward direction is 6.4 km/hr
