In training for a swim meet, Logan swam 750 meters in \large \frac {1}{3} 3 1 of an hour. His swimming partner, Mila, swam \frac {2}{3} 3 2 of Logan's distance in \frac {1}{4} 4 1 of an hour. what is milas average speed

Answers

Answer 1

Answer:

Answer:

2 km/hr

Step-by-step explanation:

Distance traveled by Logan = 750 m = 0.75 km = $(3)/(4)\ km$

Time taken by Logan = $(1)/(3)\ hours$

To calculate the speed using time and distance, following formula is used:

$\text{Average Speed =} \frac{\text{Total Distance}}{\text{Total Time}}$

Speed of Logan :

$((3)/(4))/((1)/(3))\n\Rightarrow \frac{9}4\ km/hr$

Distance traveled by Mila = $(2)/(3)$ of Logan's distance:

$(2)/(3)* (3)/(4) = (1)/(2)\ km$

Time taken by Mila = $(1)/(4)\ hr$

As per formula above:

Average Speed of Mila is given as:

$((1)/(2))/((1)/(4))\n\Rightarrow (4)/(2)\n\Rightarrow \bold{2 km/hr}$
