CLASS-7


CHAPTER-MOTION AND TIME

Answer 1

AnSwEr :-

===================================

⊙ Refer to the attachment

For slope :-

Horizontal distance / vertical distance

= 90 / 60 = 1.5 units

Answer 2

SUBJECT

PHYSICS

TOPIC.

MOTION ( distance time graph)

GRAPH .

LOOK IN ATTACHMENT .

SLOPE

FORMULA

$slope = \frac{dx}{dt}$

More information=>

mean slope represent the speed at that point

ABOUT GRAPH

Graph is straight line graph. which mean that speed remain constant in whole jeroney.

$slope = \frac{20 - 10}{9.45 - 9.30 } = \frac{10km}{0.15m}$

so,speed

$\frac{10}{0. 15} \frac{km}{m}$

$\frac{200km}{3m}$


66.6 km /m
