Question

What is the length of the best jump of a girl competing in a long jump competition if her first jump is 4.25m and her best jump is 12% more than this?

Answer 1

To find the length of the best jump, we start with the first jump of the girl, which is 4.25 meters. To calculate the best jump, which is 12% more than her first jump, we first need to find 12% of 4.25 meters.

We calculate 12% of 4.25 meters:

\[
12\% \text{ of } 4.25 = \frac{12}{100} \times 4.25 = 0.12 \times 4.25 = 0.51 \text{ meters}
\]

Next, we add this amount to her first jump:

\[
\text{Best jump} = 4.25 \text{ meters} + 0.51 \text{ meters} = 4.76 \text{ meters}
\]

Therefore, the length of the best jump is:

\[
\boxed{4.76} \text{ meters}
\]
