Step-by-step explanation:
The applicable relationship between speed, distance, and time is ...
time = distance/speed
= (3 km)/(150 km/h) = (3/150) h = 1/50 h
= (60 min)/50 = 1.2 minutes

Answer:
8(23) so 184
Step-by-step explanation:
L*w=20, so l=20/w
l=2w+3
20/w=2w+3
20=2w^2+3w
2w^2+3w-20=0
Slip and slide
w^2+3w-40
(w+8)(w-5)
(w+8/2)(w-5/2)
(w+4)(2w-5)
w= -4 or 5/2, but since width must be positive, it is 5/2
(5/2)*l=20
l=8
Final answer: Length= 8, Width= 5/2
