One of the track and field events is the triple jump. In this event, the
athlete takes a running start band makes three jumps without stopping. Find
the total length of 3 jumps for an athlete who jumped 643feet on the first
one, 1723feet on the second jump and 1815feet on the last jump.
+592 We can add the 3 numbers together:
$\frac{64}3+17\frac23+18\frac15=$
$21\frac13+17\frac23+18\frac15=$
$39+18\frac15=\boxed{57\frac15}$
