Answer 1

here is ur answer
hope u could able to understand it

Answer 2

Case1:
ABOUT BUS
Distance covered :320km
Time taken:8 hours
speed : ?
avg. vel. : ?

Ans:
speed = distance÷time
= 320÷8=40
40km/h

In this case, speed is uniform at every time interval. Thus,
Avg . vel. = displacement÷time
= 320÷8=40
= 40 km/h


Case2:
ABOUT PLANE
Distance covered:240km
Time taken:15 min = 15/60 =1/4 hours
speed:?
Avg.vel.:?

Ans:
speed =distance÷time
=240÷ 1/4
=240×4
=960km/h

In this case,as well,speed is uniform at every time interval.Thus,
Avg.vel.=displacement÷time
=240÷1/4
=240×4
=960 km/h
