Answer:
The parachuter is falling at a speed of 31.667 meters per second.
Explanation:
Given that parachuter falls at constant speed and travelled distance and time are known, the unknown is speed, measured in meters per second, which is obtained by the following kinematic expression:
Where:
- Travelled distance, measured in meters.
- Time, measured in seconds.
If and
, the speed of the parachuter is:
The parachuter is falling at a speed of 31.667 meters per second.
Total distance between Sally's house and mall = 10 kilometers
Distance covered during half way drive = Kilometers
Now, she goes back to her home.
Distance covered going back home = Kilometers
Now, she drives from home to mall.
Distance covered from Sally's home to mall = 10 kilometers
Hence, the total distance Sally traveled = 5 + 5 + 10
Total distance Sally traveled = 20 kilometers
Hence, the answer is 20 kilometers
