Explanation:
Question is incomplete
Assuming the question you have asked is
You are driving home from school steadily at 95 km/h for 180 km. It then begins to rain and you slow to 65 km/h. You arrive home after driving 4.5 h.
given,
speed of 95 km/h for 180 km
due to rain
speed is reduced to 65 km/h
distance traveled in 4.5 hour
time taken to travel 180 km
d = s x t
![t = \dfrac{180}{95}](https://tex.z-dn.net/?f=t%20%3D%20%5Cdfrac%7B180%7D%7B95%7D)
t = 1.9 hr
distance traveled in time, t' = 4.5-1.9 = 2.6 hr
Speed of vehicle = 65 Km/h
d' = s x t'
d' = 65 x 2.6
d'= 169 Km
total distance your hometown from school
D = d + d'
D = 180 + 169
D = 349 Km

Answer
given,
before collision
mass of car A = m_a = 1300 kg
velocity of car A = v_a = 35 mph
mass of car B = m_b= 1000 kg
velocity of car B = v_b = 25 mph
after collision
V_a = 30 mph
V_b = 31.5 mph
Initial momentum
![P_1 = m_av_a + m_b v_b](https://tex.z-dn.net/?f=P_1%20%3D%20m_av_a%20%2B%20m_b%20v_b)
![P_1 = 1300 \times 35+ 1000 \times 25](https://tex.z-dn.net/?f=P_1%20%3D%201300%20%5Ctimes%2035%2B%201000%20%5Ctimes%2025)
![P_1 =70500 Kg.m/s](https://tex.z-dn.net/?f=P_1%20%3D70500%20Kg.m%2Fs)
final momentum
![P_2 = m_aV_a + m_b V_b](https://tex.z-dn.net/?f=P_2%20%3D%20m_aV_a%20%2B%20m_b%20V_b)
![P_2 = 1300 \times 30+ 1000 \times 31.5](https://tex.z-dn.net/?f=P_2%20%3D%201300%20%5Ctimes%2030%2B%201000%20%5Ctimes%2031.5)
![P_2 =70500 Kg.m/s](https://tex.z-dn.net/?f=P_2%20%3D70500%20Kg.m%2Fs)
here initial momentum is equal to the final momentum of the car.
hence, momentum is conserved in the collision.
Trade winds near equator blows in curve path instead of straight path. This is because of earth rotation. This effect of earth rotation that cause wind to move in curve motion is called Coriolis effect. These kind of wind blows at the northeast of the North hemisphere and southeast of the South hemisphere. The trade wind are warm and it blows due to rising of hot air from equator.
