Answer 2

EXPLANATION-

find the speed of the car between 12:00 hours to 12:30 hours

time = 12:30 - 12:00 = 30 mins = 1/2 hr

Distance = 65-30 = 35 km

average speed = distance/ time taken

= 35/(1/2) = 70 km/hr

what is the average speed of the car

total time = 1:00 pm = 13:00 - 11:00 = 2 hrs

distance = 100 km

speed = 100/2 = 50 km/ hr

iii)- is the car's motion is an example of uniform motion

-No

1st -1/2 hr 60 km/ hr

2nd- 1/2 hr 0 km/ hr

next 2 1/2 hrs 70 km/ hr
