Question

A watermelon seed is 4mm long. How far would a line of 114 watermelon seeds stretch? Write your answer in meters.

Answer 1

The answer is 0.456 m.

Explanation:

The length of 1 watermelon seed is 4 mm.

The length of a line of 114 watermelon seeds is 114 x 4 = 456

We now have to convert 456 mm to meters.

--------------- | ------ Unit ------- | Symbol | ------- Fact -------- |

--------------- | -- millimeter --- | -- mm -- | - 100 mm = 1 m - |

--------------- | - centimeter -- | --- cm -- | - 100 cm = 1 m -- |

Length ---- | -- decimeter -- | --- dm -- | -- 10 dm = 1 m -- |

--------------- | ----- meter ----- | ---- m --- | - - - - - - - - - - - - - |

--------------- | -- kilometer --- | --- km -- | - 1 km = 1000 m - |

In 1 meter there are 1000 millimeters.

So to convert millimeter to meters, we divide by 1000.

--------- 456 mm = (456 ÷ 1000) m = 0.456 m.

A line of 114 watermelon seeds would stretch 0.456 meters.

So our answer is 0.456 m.
