Answer 1

Part A:

Sheila travels at a speed of 6 meters per second.

Part B:

It would take Sheila 15 seconds to travel 90 meters at this speed.

Explanation:

Part A:

To calculate Sheila's speed, we divide the distance traveled (54 meters) by the time taken (9 seconds):

Speed = Distance / Time = 54 meters / 9 seconds = 6 meters per second.

Therefore, Sheila travels at a speed of 6 meters per second.

Part B:

To find the time it would take for Sheila to travel 90 meters at the same speed, we can use the formula:

Time = Distance / Speed

Plugging in the values, we have:

Time = 90 meters / 6 meters per second = 15 seconds.

Therefore, it would take Sheila 15 seconds to travel 90 meters at this speed.
