Answer 1

Given :

The Ironman endurance race has a 2.4 miles swim.

Javier can swim 0.5 miles in 20 minutes.

To Find :

How much time in hours it takes to complete the race.

Solution :

Speed of Javier :

$s=\dfrac{2.4}{\dfrac{20}{60}}\ mph\\\\s= 7.2\ mph$

Let, time taken to cover 2.4 miles is t .

So,

$t = \dfrac{2.4}{7.2}\ hours\\\\t = 0.33\ hours$

Hence, this is the required solution.
