Answer:
The car travel 44 feet during the driver`s reaction time.
Step-by-step explanation:
The sentence "If the driver`s reaction time was 34 of a second" has to be changed as "If the driver`s reaction time was 3/4 of a second"
If the driver drives at a speed of 40 miles per hour, it means s/he travels
40 × 5280 = 211200 feet per hour.
1 hour is 60 minutes and 1 minute is 60 seconds.
That is, 1 hour is 3600 seconds.
Therefore the driver travels [tex]\frac{211200}{3600}[/tex] feet in a second.
And since the reaction time is [tex]\frac{3}{4} =0.75[/tex] of a second, the car travels [tex]\frac{211200}{3600 } * \frac{3}{4}=44[/tex] feet during the reaction time.
