- avg. speed=2xy/(x+y)
avg=2*24*36/(24+36)
avg=28.8 - 11 years agoHelpfull: Yes(3) No(2)
- 2xy/x+y;2*24*36/24+35=28.8

- avg speed=2*a*b/(a+b)
=2*24*36/(24+36)
=28.8 - 11 years agoHelpfull: Yes(1) No(0)
- avg speed=2(24)(36)/(24+36)=28.8
- 11 years agoHelpfull: Yes(0) No(0)
- avrg= (2*a*b)/a+b
2*24*36/24+36=28.8 - 11 years agoHelpfull: Yes(0) No(0)
