I am stuck with the following problem:
A frog hops and lands exactly 1 meter away at a time . What is the least number of hops required to reach a point 10 cm away ?
The options are:
1.$\,\,1$
2.$\,\,2$
3.$\,\,3$
4.It can't travel such a distance.
The answer is given to be 2. But I have no clue how to tackle it. Can someone explain. Thanks in advance for your time.
The answer is $2$. This is straightforward, as pointed out in the comment. Since a triangle can be constructed with sides $1m, 1m, $ and $10 cm$; therefore first the frog, say from point A jumps to point B $1m$ apart. Then, the frog jumps to anither point C $1m$ apart but just $10cm $ away from point A thus total displacement being $10 cm$.
