Silly Primary 6 maths questions

My tutee was sick of the dreary repetitive Maths questions in his assessment books. So I tried adding a few drops of irrelevance into the usual questions to suit him. Surprisingly, he attempted them with some enthusiasm--either he liked colourful questions or he enjoyed putting his tutor go the extra mile to stretch his dollar. Here are the questions for your amusement.

1. A container has 2500cm(3) of Coca-Cola(tm). The base of the container is 25cm by 40cm. How high will the coke rise if I throw in 8 fishes, each having a volume of 350cm(3)?

2. The ratio of Ah Meng's weight to Spidey's weight is 3:1. Spidey's weight is 60% of the total weight between Spidey and Venom. Venom weighs 60kg. What is Ah Meng's weight?

3. Spongebob is running from Jurong to Yishun at 30km/h. At three quarters of the journey, Sonic overtakes him at 65km/h. Spongebob increases his speed to 40km/h and reaches Yishun 2.5hr after Sonic.
a) Find the distance of the journet.
b) Find Spongebob's average speed.

If you're bored enough to attempt them, the answers are: 1) 2.8cm; 2) 240kg; 3a) 1040km, b) 32km/h.
