- Many employers prioritize candidates with prior work experience over fresh graduates.
- There is a large number of graduates competing for a limited number of entry-level positions.
- Employers seek specific, up-to-date skills that may not be thoroughly covered in traditional education programs.
- Fluctuating economic conditions can lead to fewer job openings and more conservative hiring practices.
- The shift to remote work has reduced networking opportunities and made it harder to secure internships that provide valuable experience.
- The lingering effects of the pandemic continue to affect job markets and hiring processes, leading to fewer opportunities.
Speeds of the Ship in Still Water and the Stream Let vsv_svs be the speed of the ship in still water and vcv_cvc be the speed of the current. The downstream speed vdv_{d}vd is given by: vd=vs+vc=77 km/hv_{d} = v_s + v_c = 77 \text{ km/h}vd=vs+vc=77 km/h The upstream speed vuv_{u}vu is given bRead more
Speeds of the Ship in Still Water and the Stream
Let vs be the speed of the ship in still water and vc be the speed of the current.
The downstream speed vd is given by: vd=vs+vc=77 km/h
The upstream speed vu is given by: vu=vs−vc=67 km/h
Adding and subtracting these two equations: vs+vc+vs−vc=77+67 2vs=144 vs=72 km/h
vs+vc−(vs−vc)=77−67 2vc=10 vc=5 km/h
Therefore, the speed of the ship in still water is 72 km/h and the speed of the stream is 5 km/h
