There are 7 girls on a bus.
each girl has 7 backpacks.
In each backpack there are 7 big cats.
For every big cat there are 7 little cats.
Question: How many legs are there in the bus?
I interpreted this question differently than Tim. Here's what I came up with:
7 girls x 2 legs each = 14 legs
If each girl has 7 backpacks and there are 7 big cats in each....49 backpacks x 7 cats=343 big cats. Then, there are 7 little cats for each big ...343x7=2401 little cats.
Total cats 2401+343=2744 total cats which have 4 legs each, so there are 10976 cat legs. Add this to the 14 girl legs and you get 10990 total legs. You might check to be sure this is what you need.
7 LITTLE CATS x 4 LEGS = 28
28 X 7 = 196 LITTLE CATS LEGS
7 BIG CATS X 4 LEGS = 28
7 GIRLS X 2 LEGS = 14
BUS DRIVER HAS 2 LEGS
196 + 28 + 14 + 2 = 240
Thank you so much!! I will see if that is correct.
MSP- Your answer was correct. 10990.
Thank you again!!
To find the total number of legs on the bus, we need to determine the number of legs contributed by each component - the girls, the backpacks, the big cats, and the little cats.
First, we count the number of legs from the girls. Since each person has two legs, and there are 7 girls on the bus, the total number of legs from the girls is 7 × 2 = 14.
Next, we consider the backpacks. Although it's not explicitly mentioned in the question, we assume that backpacks do not have legs. Therefore, the backpacks do not contribute any legs to the total count.
Moving on to the big cats, we know that each big cat has 4 legs. The number of big cats can be calculated by multiplying the number of backpacks (7 backpacks per girl) by the number of girls (7 girls in total). So, the total number of big cats is 7 × 7 = 49. Multiplying this by the number of legs per big cat (4 legs) gives us 49 × 4 = 196 legs.
Finally, we consider the little cats. The number of little cats can be calculated in the same way we did for big cats: multiplying the number of backpacks (7 backpacks per girl) by the number of girls (7 girls in total). So, the total number of little cats is 7 × 7 = 49. Since each little cat has 4 legs, the total number of legs from the little cats is 49 × 4 = 196 legs.
To calculate the total number of legs on the bus, we add up the number of legs from each component:
Legs from girls (14) + Legs from big cats (196) + Legs from little cats (196) = 406 legs.
Therefore, there are 406 legs in the bus.
