Answer 1

2. distance= 360 km
time = 4 hours
speed = distance/ time
= 360/4
= 90 km/ hr
hence its speed is 90km/ hr

3.distance = 450 km
time= 10 hr
speed = distance / time
= 450/10
= 45 km / hr
hence its speed is 45 km/ hr

8 (a)36 km per hr
36× 1000/3600
= 10 meter per second

(b) 60 km per hr
60 × 1000/3600
=50/3 meter per sec

(c) 126 km per hour
126× 1000/3600
= 35 meter per second
