Answer:
912.414
Step-by-step explanation:
The angle
θ
between the directions of motion of planes
θ
=
320
−
200
=
120
∘
The distance
a
traveled by first plane flying at a speed of
150
km/hr
in
3
hrs
a
=
150
⋅
3
=
450
k
m
Similarly, the distance
b
traveled by second plane flying at a speed of
200
km/hr
in
3
hrs
b=
200x3=
600 km
Now, the distance between the planes after 3
hrs will be equal to the side of a triangle opposite to the angle θ=120∘
included by the sides
a
=
450
& b=
600
.
Now, using Cosine rule in the concerned triangle, the distance between the plane after
3
hours is given as
Just add all of the numbers up and then divide 6 because they're 6 families.

Answer:
50 2/5
Step-by-step explanation:
7 2/10 can be converted to 72/10
72/10 x 6 is 432/10
432/10 simplified is 43 2/10
7 2/10 + 43 2/10 is 50 2/5
Ok so important numbers 42 ft, 2cm, 3 ft and lets take height as x
if 2cm=3ft than x cm= 42 ft
2 = 3
-------
x= 42
cross multiply divide
(42)2/3
84/3
