Question

Solve.

A European swallow flies about 12 meters in 1 second.
How many kilometers could it fly in 15 minutes?
It could fly |​

Answer 1

It could fly 10,8 kilometers.

Explanation:

The European swallow fly speed is 12 meters per second.

We have to calculate how many kilometers it could fly in 15 minutes.

This can be calculated using the equivalent factors for each of the units:

- 1 km is equivalent to 1,000 meters.

- 1 minute is equivalent to 60 seconds.

We know that the distance travelled by the fly is the product of the speed and the time, so we have:

`D=v\cdot t\\\\\\D=12\,(m)/(s)\cdot15\, min\\\\\\D=12\,(m)/(s)\cdot((1\,km)/(1,000\,m))\cdot15\, min\cdot ((60\,s)/(1\,min))\\\\\\D=(12\cdot 15\cdot 60)/(1,000)\,km=(10,800)/(1,000)\,km\\\\\\D=10,8 \,km`
