Answer:
52 km/hr
Step-by-step explanation:
Speed equals distance over time.
2 hours 45 minutes = 2.75 hours
S = 143/2.75
S = 52
The car’s speed is 52 kilometers per hour.
2 1/9 as improper fraction= 19/9
19/9(4/4)=76/36
7/6(6/6)= 42/36
76/36-42/36=34/36
34/36=17/18
The answer is 17/18.
Hope this helps!
The airplane's speed in the direction of its heading is
.. 410 mph +r*cos(θ)
where θ is the angle between the plane's heading and the direction the wind is moving toward.
That is, if the plane is moving "with the wind," its speed is (410 +r) mph.
If the plane is moving "against the wind", its speed is (410 -r) mph.
