Question

Henry watches a flock of $68$ sheep jump over a fence, one sheep at a time. Each sheep takes about $2$ seconds to jump the fence. How much time will it take all the sheep to jump over the fence?

• A. $68$
• B. $136$

Answer 1

The correct option is B $136$

Total number of sheep $=68$
Time taken by $1$ sheep $=2$ seconds
Time taken by $68$ sheeps $=68\times 2$ seconds

The product $68\times 2$ can be evaluated as:



$2\times 68$ seconds $=136$ seconds
The time taken by all the sheeps to jump over the fence would be $136$ seconds.
