Answer 1

Answer:

4 minutes 30 seconds

Step-by-step explanation:

Given:

Erica can run 1/6 of a kilometer in one minute.

Her school is 3/4 of a kilometer away from her home.

Question asked:

How long would it take Erica to run home from school = ?

Solution:

As here distance is  given and also speed is given, we will find time taken to run from home to school by using,

$Speed=\frac{Distance}{Time} \\ Time =\frac{Distance}{Speed}$

         $=\frac{3}{4} \div\frac{1}{6} \\\\ =\frac{3}{4} \times\frac{6}{1} \\\\ =\frac{18}{4} \\ \\ =\frac{9}{2} \\ =4.5 \ minutes$

Therefore, it takes 4 minutes 30 seconds Erica to run home from school.
