Question

A car driving on a straight path travels about 260 feet in 3 seconds. Rounded to the nearest second, approximately how many seconds will it take for the car to travel 1 mile at the same rate? 1 mile = 5,280 feet

Answer 1

Hello!

Let's write this as a proportion below.

$\frac{feet}{seconds} = \frac{260}{3} = \frac{5,280}{s}$

Now we cross multiply and divide to find x.

$s= \frac{5,280(3)}{260} = \frac{15840}{260}$ ≈ 61

Therefore,the car takes about 61 seconds for the car to drive a mile.

I hope this helps!

Answer 2

1 mile = 5,280 feet

Let s = seconds we must find

260/5,280 = 3/s
