It took 45 seconds to reach 2550 ft for Frank and his friends
Solution:
Given, Frank goes skydiving with his friends.
As they exit the plane at 3000 ft, they start to fall at approximately 10 ft per second.
We have to find how long does it take them to reach 2,550 ft
Now, we know that, distance travelled = speed x time
Then, in our case, 3000 ft – 2550 ft = 10 ft per second x time taken
So, 3000 – 2550 = 10 x time taken
10 x time taken = 450
Time taken = 45 seconds.
Hence, they took 45 seconds to reach 2550 feet
