Answer:
About 300 minutes
Step-by-step explanation:
She can eat 41 jelly beans in 10 minutes and she has eaten 1231
You need to divide 1231 by 41 (then you will know how many sets of 41 jelly means she ate)
It will give you 30.024390...
and if she at this many sets of 41 and each 41 is 10 minutes,
then you have to multiply 30 by 10
you get about 100 minutes
I think :)
