Answer:
1. Distance: 450 km
Time: 5 hrs
Speed:90 km per hour.
Step-by-step explanation:
450 (distance) Then divided to
5 hours (time)
450÷5=90
So 90 km per hour is the speed of the bus
2. a = 40 m/s - 20 m/s ÷ 10 seconds
= 20 m/s ÷ 10 s
a = 2 m/s 2 or squared
3. Distance = speed ÷ time.
Thus the distance is 60 ÷ 5= 12 km.
4. Time = Distance ÷ speed.
Thus the time is 12 ÷ 6= 2 hours.
5. V = a x t
A = v / t
The average acceleration is (90 km/hr)/(3 hr) = 30 km/hr/hr
