Question

Santiago's car has an overall average speed of 25 cm/s. If he could increase his car's overall average speed by 10%, what would his car's new overall average speed be?

Answer 1

Given:

The overall average speed = 25 cm/s.

The overall average speed increased by 10%.

To find:

The new overall average speed.

Solution:

We have,

Overall average speed = 25 cm/s.

The overall average speed increased by 10%. So, the new average speed is

New overall average speed = Initial average speed + 10% of initial  overall average speed

$\text{New overall average speed}=25+\dfrac{10}{100}\times 25$

$\text{New overall average speed}=25+2.5$

$\text{New overall average speed}=27.5$

Therefore, the new overall average speed is 27.5 cm/s.
