Jenny's frog jumped 0.23 m more than Christina's did on both jumps combined.
The question requires the difference between the distance jumped by Jenny's frog and that jumped by Christina's.
First thing you need to do is to find out the total distance jumped by Christina's frog:
= 1.22 + 0.89
= 2.11 m
The distance jumped by Jenny's frog more than Christina's is:
= Jenny frog distance - Christina frog distance
= 2.34 - 2.11
= 0.23 m
In conclusion, Jenny's frog jumped 0.23 m more than Christina's.
