It's definitely not the first option, since the student first "slowly" walked to the bus station. Also, the student waited and stopped, so the speed should have been zero.
It's most likely the second option. The speed increases, stays constant, and increases again, which is exactly what's happening to the car's speed.
I'd choose the second choice.
Have an awesome day! :)
Answer:
x=10 is answer.
Step-by-step explanation:
2 (x-1/8)-3/5x=55/4
2x/1-1/4-3/5=55/4
40x/20-5/20-12x/20=55/4
28x-5/20=55/4
112x-20=1100
112x=1120
x=1120/112
x=10
