Question

An airplane can fly at a speed, that allows it to fly 50 yards in 3⁄2 of a second. How long will it take an airplane at the same speed to fly 20 yards? Write your answer as a fraction of a second

Answer 1

Answer:

$x = \frac{20 \times 3}{2 \times 50} \\ x = \frac{3}{5} sec$

Answer 2

Hey there,

Let's get started !

50 yards ==> 3/2 of a second
20 yards ==> x sec

You have to cross multiply :

20*(3/2)/50
= 30/50
= 3/5 sec.

The answer is 3/5 of a second.

Hope this helps !
