The average speed of the car is 19.62 km/hr.
'<em>Your question is not complete, it seems to be missing the following information'</em>
find the average speed of the car
The given parameters;
initial velocity of the car, u = 25 km/hr
time of motion of the car, t= 1.5 hr
final velocity, v = 21 km/h
time of motion, = 1.25 hr
The average speed of the car is calculated as follows;
Thus, the average speed of the car is 19.62 km/hr.

charge = current * time
q = 15 * 300 [5 min = 300 sec ]
q = 4500 C
Answer:
0.333 i1
Explanation:
from figure
iB = i2
i1 = iA
i1 = iA = iB+iC = i2+iC
all resistances are equal o R
i1 = E/[R + 2R||R + R] = E/[8R/3] = 3E/8R
since if v is constant then i is inversely proportional to R
iB/iC = R/2R = 1/2
iC = 2iB = 2i2
and i1 = iB+iC = iB+2iB => i1 = 3iB = 3i2
thus i2 = i1/3
or
the equivalent resistance is
Req = [R || (R+R) ] + ( R + R)
Req = 2R/3 + 2R = 8R/3 ohm
current i1 = E / Req = E / ( 8R/3) = 3E/8R
i1 is divided in two parts as i2 = ib and ic
i1 is divided in i2 and ic in ratio 1 :2
Twice the current will flow through RC as will flow through RB and R2. So the current flowing in R1 and RA is divided by 3,
so i2 is 0.33*i1
i2 = [ 1 / (1+2) ] * i1 = 1/3 * i1
i2 = i1 / 3 = 0.333 i1
