Alyssa takes part in the triathlon. She cycles 4/5 of the route, runs 7/8 of the route, and swims the rest of the way. She swims 0.9 miles. Find the total distance of the triathlon route.

Answer 1

I suspect a typo, since 4/5 + 7/8 > 1
Now, if you meant to say she ran 7/8 of the way from the cycled part to the end, then
4/5 x + 7/8 * 1/5 x + 9/10 = x
x = 36
check:
4/5 * 36 = 28.8
7/8 * (36-28.8) = 6.3
28.8+6.3+0.9 = 36.0
