Question

distance is equal to:
a) speed × time
b) speed by time
c) displacement ×time
d) displacement/time​

Answer 1

Answer:

Correct option is

C

2:1

Slope of displacement-time curve gives the speed.

For first 2 seconds, speed v=

2

40

=20 m/s

For the last 4 seconds, speed v=

4

40

=10 m/s

Hence, ratio =20/10=2:1

Answer 2

Option A ...

speed × Time
