Answer:

17.24

Step-by-step explanation:

Simple subtraction of decimals because the other runner was faster:

23.10

-5.86

=

17.24

The other Runner's time ​is 17.24 seconds.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

Given that Anna's running time for a race was 23.1 seconds

And another runner's time was 5.86 seconds faster

It took Anna 23.1 seconds to complete a race.

Since the other runner was quicker,

So we did a simple decimal subtraction,

⇒ 23.10 - 5.86

⇒ 17.24

So, It took other runners 17.24 seconds to complete a race.

Hence, the other Runner's time ​is 17.24 seconds.
