Adam and Eve live 20 km apart. They are going to a meeting. Adam moves at a speed of 2 km/h faster than Eva. They will meet in one and a half hours. Determine their speeds.

Correct answer:

v1 =  7.6667 km/h
v2 =  5.6667 km/h

Step-by-step explanation:

t=1.5 h s=20 km  v1 t+v2 t=s v1=2+v2 v1 1.5+v2 1.5=20 v1=2+v2  1.5v1+1.5v2=20 v1v2=2  Row21.51 Row1Row2 1.5v1+1.5v2=20 2v2=11.33  v2=211.33333333=5.66666667 v1=1.5201.5v2=1.5201.5 5.66666667=7.66666667  v1=3237.666667 v2=3175.666667
