A cargo plane flew from the US across the Atlantic at 212 mph, and flew back to the US at 232 mph. Given that the first trip took two hours longer, how long was the return trip?

Respuesta :

absor201

The return trip was 21.2 hours long.

Step-by-step explanation:

Given,

Speed of plane from US = 212 mph

Speed of plane on return trip = 232 mph

Let,

x be the time taken on return trip.

Time taken from US = x+2

We know that;

Distance = Speed * Time

Distance of plane from US = 212(x+2) = 212x+424

Distance on return trip = 232x

As the distance will be same, therefore,

[tex]232x=212x+424\\232x-212x=424\\20x=424[/tex]

Dividing both sides by 20

[tex]\frac{20x}{20}=\frac{424}{20}\\x=12.2\ hours[/tex]

The return trip was 21.2 hours long.
