Lingjin drove from los angeles to ventura during rush hour at an average speed of 4545 miles per hour, and then drove back the s

Softa [21]

45mph times x hours one way
30mph times y hours back
x+y=3 hours 15 minutes

45mph(x)=z miles
30mph(y)=smiles
so
$45x = 30y \\ x = \frac{30}{45} y \\ x = \frac{2}{3} y$
and substituting we know 15 minutes is 1/4 an hour so we have
$x + y = 3.25 \\ \frac{2}{3} y + y = 3.25 \\ \frac{5}{3} y = \frac{13}{4} \\ y = \frac{13}{4} ( \frac{3}{5} ) \\ y = \frac{39}{20}$
so 1.95 is how long they were going 30mph
1.95hours time 30mph is 58.5 miles.
so that is the distance. check by putting in y and solving for x. multiply x by 45 and you should get the same distance
