Answer:
2a) x = 32 [mil/h]; 2b) t = 0.5[h]; 3a) t = 2.5 [h]; 3b) x = 185[mil]
Explanation:
2a)
We can solve this problem by using the kinematics equation, which relates speed to time and displacement.
2b)
We can solve this problem by using the kinematics equation, which relates speed to time and displacement.
3a)
We can solve this problem by using the kinematics equation, which relates speed to time and displacement.
3b)
We can solve this problem by using the kinematics equation, which relates speed to time and displacement.
Answer:
3.75 hours
Explanation:
By
where v is the velocity (or speed in this case)
d is the distance travelled
t is the time taken
Therefore it takes 3.75 hours for the bus to travel 150 km and 40 km/hr.
