Question

Dolma wants to participate in a triathlon competition where she has to swim, cycle and
run some distances. The cycling distance is 4 times the swimming distance. The running distance is 4 km more than the swimming distance, and is 14 km less than the cycling distance. Find the total distance of the race.
​

Answer 1

Answer:

40

Step-by-step explanation:

Let us consider Swimming = X

Cycling = 4X

Running = X+4

Also Running = 4X-14

Thus, 4X-14 = X+4 (solve linear equation)

4X-X=4+14

3X=18

X=6  

Swimming = 6; Cycling = 24 and Running = 10

6+24+10 = 40
