Answer:
Correct option is
A
252 metre
Let the distance traveled in 315 minutes be x km.
Time ( in minute ) 125 315
Distance ( in meter ) 100 x
If the distance traveled is more, the time needed to cover it will also be more.
∴ It is a direct variation.
125:315=100:x
⇒
315
125
=
x
100
⇒ x=
125
100×315
⇒ x=252
∴ Anupama would cover 252 meter in 315 minutes.
