Total distance traveled = 74 + 83 = 157 km.
Total time traveled = 1 + 5 = 6 hours.
Average speed = total distance / total time
Average speed = 157 km / 6 hours = 26.1666 km per hour.
Round the answer as needed.
As it is given to us
also it is given that
P - Q + R = 0
so here we can rearrange it to find the value of R
so here we have
so the vector is given by above equation

Answer:
8.66m/s2
Explanation:
from newton second laws F=ma
the force down the plane is the component force along the plane which is mgsin₩ so there fore
a= gsin₩ = 10sin60= 8.66m/s2
