Question 14 Bald eagles are known to fly as high as 4500 – 6000 m above the ground level. Mount Everest is about 8850 m high. Aeroplanes can fly as high as 10,000 – 12,800 m. How many times bigger are these heights compared to Somu’s building?For Somu’s building Each floor is 4 m There are 10 floors Total height of Somu’s building = 4 × 10 = 40 m Let's compare this to the other heights: 1. Bald Eagles vs. Somu's Building: Bald eagles fly as high as 4500 – 6000 m. At 4500 m: 4500 m÷40 m=112.5 times At 6000 m: 6000 m÷40 m=150 times Bald eagles can fly approximately 112.5 to 150 times higher than Somu's building. 2. Mount Everest vs. Somu's Building: Mount Everest is about 8850 m high. 8850 m÷40 m=221.25 times Mount Everest is approximately 221.25 times bigger than Somu's building. 3. Aeroplanes vs. Somu's Building: Aeroplanes can fly as high as 10,000 – 12,800 m. At 10,000 m: 10000 m÷40 m=250 times At 12,800 m: 12800 m÷40 m=320 times Aeroplanes can fly approximately 250 to 320 times higher than Somu's building
