Hope this helps! :D
Try this solution:1. If l/m=5/2:5/3, then l/m=3/2 and l=3/2 m;2. If m/n=5/4:7/2, then m/n=5/14 and n=14/5 m;3. l/m/n= 3/2 m: m: 14/5 m; ⇒ l/m/n=3/2:1:14/5 (or l/m/n=15/10/28).
1. 18.6 +8.7
2. 104-54 then that number /1
The time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds
Given the equation representing the height reached by a rocket as:

The rocket will hit the ground when y = 0. Substituting y = 0 into the expression to get x;

On factorizing:
x = 10.43 seconds
Hence the time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds
