Answer

Therefore, ball 1 was thrown with a faster speed.

Work Step by Step

Anita is running to the right at a speed of 5 m/s. Since Anita says that ball 1 is approaching her at 10 m/s, ball 1 must be moving at a speed of 15 m/s with respect to the ground. Since Anita says that ball 2 is approaching her at 10 m/s, ball 2 must be moving at a speed of 5 m/s with respect to the ground. Therefore, ball 1 was thrown with a faster speed.
