Final answer:
To calculate the time taken by the shuttle to travel half the distance, we can use the equation 0.25 times the total travel time. So, the correct option is a) 0.25 times the total travel time.
Step-by-step explanation:
To calculate the time taken by the shuttle to travel half the distance, we can use the equation 0.25 times the total travel time. Let's say the total travel time is T. To find the time taken to travel half the distance:
- Calculate 0.25 * T.
- That will give you the time taken to travel half the distance.
So, the correct option is a) 0.25 times the total travel time.
