Question

Kaitlyn enters a triathlon at school. In the triathlon she must swim, ride, and run. She must swim for x metres. She has to run 3 times as far as she swims, and ride 5 metres more than she swims. 

If the total length of the triathlon is 1000 m, how far must she ride?

anonymous · Answer

Where x is the length Kaitlyn swims:
1000 = x+3x+(x+5)
1000 = 5x+5
5x = 995
x = 995/5 = 199

Riding is 5m more than 5
Riding = 199+5 = 204
