Acar is traveling at a speed of 54 mph. what is the cars speed in feet per second? how many feet will the car travel in five seconds?

Car speed is 79.2 feet per second.

Car will travel the distance of 396 feet in 5 seconds.

Step-by-step explanation:

Given speed of car is 54 mph

We need to find the speed of car in feet per second

Now we know that,

1 miles = 5280 feet

1 hour = 3600 sec

hence 54 mph =  

Car speed is 79.2 feet per second.

Now we need to find the distance in 5 seconds

Distance = Speed time =

Hence Car will travel the distance of 396 feet in 5 seconds.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
