Question

How long in seconds will it take a car traveling at 100 miles/hour to travel the length of an American Football field?

Answer 1

It will take 2.45 seconds.

Step-by-step explanation:

A football field measured 120 yards, that is arround 0.068 miles, the car is moving with a constant speed so the formula we have to apply for this is:

`t=(x)/(v)\\where\\x=distance\\v=speed\\`

`t=(0.068)/(100)\\t=0.00068hrs`

in order to obtain the time in seconds:

`tsec=0.00068hr*((3600sec)/(1hr) )\\tsec=2.45 sec`
