Answer:
12 times
Step-by-step explanation:
if she jumped 10 times every 15 hours
10-15hours
that means that she jumped 2 times every 3 hours. i worked this out by dividing 10 and 15 by 5 becuase i need to make it fair on both sides. now that i know she jumped 2 times every 3 hours ,every 18 hours lois would jump 12 times .
i hope this helps
