Hope this helps!!!
Answer is: 158,5 km.
<span>1.87e3 m is 1870 m /1000 = 1,87 km.
</span><span>24 m is 24 / 1000 = 0,024 km.
</span><span>5.43e-1 km is 0,587 km.
</span><span>1.561e2 km is 156,1 km.
</span>summing: 1,87 km + 0,024 km + 0,587 km + 156,1 km = 158,5 km.
e3 means 10³ (10 · 10 · 10 = 1000).
