Correct answer is C
P(67°W, 0°N)
Q(67°W 90°N), R = 6400km
Distance PQ =
90/360 x 2 x 6400 π
= 3200πkm

Correct answer is C
P varies inversely as the square of W. When W = 4, P = 9. Find the value of P when W = 9
729/16
6
4
16/9
4/3
Correct answer is D
P α 1/w2; P = K/W2
9 = K/42; 9 = K/16
K = 9 x 16 = 144
P = K/W2; when w = 9
P = 144/92 = 144/81 = 16/9
Make q the subject of the relation t = √(pq/r - r\(^2\)q)
q = \(\frac{rt^2}{(p - r^3)}\)
q = \(\frac{t^2}{(p - r^2)}\)
q = \(\frac{rt}{(p - r^3)}\)
q = \(\frac{(p - r^3)}{rt^2}\)
q = rt\(^2\)(p - r\(^3\))
Correct answer is A
t = √pq/r - r\(^2\)q
multiply both sides by the L.C.M, r
r\(^2\) = pq - qr\(^3\)
collect like terms on the RHS
q(p - r3) = rt\(^2\)
q = \(\frac{rt^2}{(p - r^3)}\)
