Question

After driving for 4 hours Nancy discovered that she had driven 362 miles. How fast was Nancy driving?

Answer 1

Given:

The number of hours Nancy drove = 4 hrs

The distance that she traveled = 362 miles

The word 'fast' speaks of speed. Speed is the rate at which something moves. Mathematically, it is the distance covered divided by time.

`\text{speed = }\frac{distance\text{ }}{time}`

Substituting the given values into the formula above:

`\begin{gathered} \text{speed = }\frac{362\text{ miles}}{4\text{ hrs}} \\ =\text{ 90.5 miles /hr} \end{gathered}`

Hence, Nancy's speed was 90.5 miles/hr

Answer: 90.5 miles/hr
