Charlotte is driving at 58.6 mi/h and receives a text message. She looks down at her phone and takes her eyes off the road for 4

kramer

Answer: 19.71 feet

Explanation:

Given: Speed of Charlotte =58.6 mi/h

Since 1 hour = 3600 seconds

and 1 mile = 5280 feet

So, Speed of Charlotte = $\dfrac{58.6\times5280}{3600}\approx85.95$ mi/ sec

She looks down at her phone and takes her eyes off the road for 4.36 s.

Since , Distance = $\dfrac{speed}{time}$

So, Distance = $\dfrac{85.95}{4.36}=19.71\ feet$

Hence, Charlotte traveled 19.71 feet during this time.
