Step-by-step explanation:
given,velocity = 5 m/s
and distance=12×1000=12000m
now,time =?
we have , v=s/t
or, t= s/v
so,t=12000/5
2400sec.....ans
=

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
2v + 3v + 75 = 180
<u>Step 2: Solve for </u><em><u>v</u></em>
- Combine like terms: 5v + 75 = 180
- Isolate <em>v</em> term: 5v = 105
- Isolate <em>v</em>: v = 21
" the sum " means add
17 + 2x = 87
2x = 87 - 17
2x = 70
x = 70/2
x = 35 <==
