Answer: 1.5 hours
Step-by-step explanation:
Softball was practiced for 2 hours each day.
After 7 days she must have practiced it for;
= 7 * 2
= 14 hours
She practiced both piano and softball for a total of 24.5 hours. She therefore practiced piano for;
= 24.5 - 14
= 10.5 hours
If in 7 days she practiced piano for 10.5 hours, everyday she must have practiced piano for;
= 10.5/7
= 1.5 hours
