Answer 1

Step-by-step explanation:

Given Two men a and b travel from point p to q, a distance of 84 km at 12 km/h and 16 km/h, respectively. B reaches q and returns immediately and meets a at r. Find the distance from p to  r

• Given D = 84 km, a = 12 km/h, b = 16 km / h
• We know that
• Distance travelled by A = PR
•                                           = 2D x a/a + b
•                                          = 2 x 84 x 12 / 12 + 16
•                                         = 2 x 84 x 12 /  28
•                                         = 72 km

Therefore distance from p tor will be 72 km.
