Question

If there were 49 cars in a line that stretched 452 ​feet, what is the average car​ length? Assume that the cars are lined up​ bumper-to-bumper. Round your answer to the nearest tenth of a foot.

Answer 1

The average car​ length = 9.2 ft.

Explanation:

Here, the number of cars lined up = 49

The total stretched length of the cars = 452 ft.

Let us assume the length of 1 car = p ft.

So, the length of 49 cars combined = 49 x ( Length of 1 car)

= 49 x ( p) = 49 p

Also, the combined length is given as 452 ft.

`\implies 452 = 49 p\\\implies   p =(452)/(49)   = 9.2244898\\\implies  p = 9.2244898`

Now, rounding off the answer to nearest tenth of a foot, we get:

p = 9.2 ft.

Hence, the average car​ length = 9.2 ft.
