Question

peregrine falcon can travel at 537000 furlong/fortnight. A race car travels at 212 feet per year. A spider can jump with a maximum velocity of 900000cm/hour. Which travels the fastest?

Answer 1

Convert the speeds of all of them into similar units. Then you can compare them.
1 furlong is 0.201168km
so a falcon travels 537000 x 0.201168 = 108027.216Km in 30 days
30 days=30 x 24 = 720hours.
so speed of falcon=distance /time=108027.216/720=150.0378Km/h
similarly convert other speeds into Km/h then you can compare the speeds to know who is the fastest.
I am in a hurry so i cannot do it for you. Sorry.
I hope this helps you
If you don't know the unit conversion, you can google it and just type converter after it(for ex. furlong to Km converter)
