nearest  mile per hour = 5

Answer 2

Tatiana's speed to the nearest mile per hour is 5 miles per hour.

Word problem in mathematics is a concept that comprises algebraic equations and arithmetic operations used to solve real-life cases.

The method that can be used to solve this relation is by equating the minutes in which Tatiana ran to hours.

Given that:

• Tatiana ran an average speed of 0.09 miles in a minute.
• 1 minute to an hour = 0.0166667 hour
• In an hour, Tatiana will run an average speed of:

0.09 miles = 0.0166667 hour

x miles =  1hour

∴

$\mathbf{x = \dfrac{0.09 \ miles \times 1 hour}{ 0.0166667 hour }}$

x = 5.40 miles per hour

x ≅ 5 miles per hour   (to the nearest mile)
