Question

P is 300 km eastward of O and Q is 400 km north of O. R is exactly in the middle of Q and P. The distance between Q and R is

Answer 1

the distance between Q and R is 350 km

Answer 2

250...100%...simply use the pythagorous theorm..

PQ² = 300² + 400²

UnderrootPQ² = underroot250000

PQ = 500km..

Since R is in the middle then distance QR =RP= 1/2 PQ = 250km
