A is 1\(\frac{1}{3}\) times faster than B. A gives 45 meter start to B in a race. Find the total distance of race if both finish the race at the same time.

180 m

                      A       :         B

Speed :         4        :         3 

Distance:      4        :         3     ⇒ 1R (start)

1R = 45,

4R = 180m = Total distance of race
