Answer:
At 15:15
Step-by-step explanation:
Given,
the 1st boy can run a lap in 15 minutes
the 2nd boy can run a lap in 25 minutes
the 3rd boy can run a lap in 10 minutes
Now if they start running at 12:45,they will meet after the time which will be equal to the L.C.M. of their time need to run a lap.
of 15,25 & 10 = 150
So,they will pass each other after 150 minutes or 2 hours & 30 minutes.
If we add it with 12:45 we'll get 15:15 or 3:15 pm
4a+11-a=2. You're going to now subtract a from 4a and you get 4a+11=2.
Next, subrtact 11 from 2 and you get 4a=-9.
Divide 9 by for and you get a=9/4 or 1 3/4.
Answer:
16

Refer to the diagram shown below.
In order for the airplane to maintain a heading of 65° west of north, it actually heads at (65° +x) west of north at a speed of 750 km/h, to compensate for the wind blowing from west t east at 60 km/h.
The actual speed of the airplane relative to the ground is V km/h.
From geometry, obtain the triangle shown.
The speed of 750 km/h is opposite an angle of 155°, and the unknown angle x is opposite the wind speed of 60 km/h.
From the Law of Sines, obtain
The heading that the pilot should take is 65 + 1.937 = 66.94° west of north.
The third angle of the triangle is 180 - (155 + 1.937) = 23.063°.
Use the Law of Sines to calculate V.
Answer:
The pilot heads approximately 67° (nearest integer) west of north.
The speed of the airplane relative to ground is 695.2 km/h (nearest tenth)
I thinks it’s B cuz you have to add plus 2 680 I think
