Question

Jackie runs and dances for a total of 55 minutes every day. She dances for 25 minutes longer than she runs.

Answer 1

Answer:

Jackie runs for $15$ minutes and dances for $40$ minutes.

Step-by-step explanation:

Let the time she dances be $x$ and the time she runs for be $y$ minutes respectively.

$x+y =55\\x =y+25$

Use the substitution method here ,

$y+25+y=55\\2y+25=55\\2y=55-25\\y=\frac{30}{2} \\y=15\\x=y+25\\x=15+25\\x=40$

Therefore Jackie runs for $15$ minutes and dances for $40$ minutes.
