Question

village P is 20km to the north of village R is 18km to the east of village Q. Village S is 12km to the west of P. If Mr X starts from village R and goes to villages S,in which direction is he from his starting point ?​

Answer 1

Answer:

Since Speed =Distance /time

Hence Time=Distance/speed

Step-by-step explanation:

P is 12km from Q

Time = 3hrs 20mins , converting to seconds we have

(3X60X60) +(30X60)

=10800 + 1800= 12,000Secs

hence

12/6 + 12/6+x = 10/3

2+12/6+x = 10/3

2(6+x)+12/(6+x)= 10/3

3[(6+x)+12]= 10(6+x)

6(6+x)+36= 10(6+x)

36+6x+36= 60+10x

72+6x= 60+10x

collect like terms

72-60= 10x-6x

12=4x

Divide both sides by 4

4x/4 =12/4

Hence x=3
