Question

while driving with his father, Amit his guys breath whenever they pass through a particular tunnel. Amit counts the number of seconds he holds his breath, from the beginning of the tunnel to the end of the tunnel, and finds he good his breath, on average, for about 8 seconds. if his father drives the car at 60 miles per hour through the tunnel, according to the average time Amit his his breath, about how long is the tunnel? (there are 5280 feet in a mile)

Answer 1

The answer is 700 feet, because if you divide 5,280 feet by 1 mile you get 88 feet per second, then you multiply 88 feet by 8 seconds you get 704 feet. Since the question said "about" I am assuming that means rounding. You round 704 to 700 and that's how you get the answer.  

Answer 2

Answer: 704 feet

Step-by-step explanation: speed of car is V= 60 miles per hour

First convert the speed from miles per hour to feet per second .

$V=\frac{60\times 5280}{60\times 60} \frac{ft}{s} = 88 \frac{ft}{s}$

Now Length of tunnel , L= speed of car x time taken

Therefore $L=88\times 8 feet=704 feet$
