Let the speed of the joker initially be x mi/hr
after reduction, the new speed will be: (x-1) mi/hr
but
time=(distance)/(speed)
hence :
Total time taken will be:
4/x+5/(x+1)=41/20
solving for x we get:
x=21.585 mi/hr
thus the initial speed was 21.585 mi/hr after reduction the new speed was 20.585 mi/hr
Answer:
x ≥ 60
Step-by-step explanation:
greater than or equal to 60
Answer:
y = -2/6 x + 2
Step-by-step explanation:
the equation will be an the y=mx+b form. therefore we know the b will be a postive 2 because thatd where it lands on the y axis and the m is the slope which is rise over run which is a negative 2/6. therefore the equation is y = -2/6x + 2
