There’s no turning point bc the multiplicity is one
Let us assume as at when they meet, the time elapsed is x hours.
Fred 3 mi/h
John 2 mi/h
Distance = speed * time
Fred = 3x
John = 2x
Houses are 4miles apart.
So: 3x + 2x = 4 5x = 4
x = 4/5 hour = 0.8 hour or 0.8*60 = 48 minutes
Time elapsed is 0.8 hour or 48 minutes.
The image is here, i am struggled with this problems too please help!
1:B, 2:A, 3:D, 4:A
those are the answers
Answer:
1/2*6(12+x)=12*x
1/2*(72+6)=12x
36+3x=12x
36=9x
4=x
Step-by-step explanation:
Check that x=4
1/2*6(4+12)=12*4
1/2*(24+72)=48
1/2(96)=48
48=48
So x=4 is the correct answer
