On a graph sheet a scale has been used. 2 cm on X axis represents 1 km in reality and 1 cm on Y - axis represents 1 km/ hr speed.

If the ratio between distance and speed of a moving vehicle is 3 : 4 and a distance of 12 kms has been covered at 16 km/hr, What will be the X - coordinate ?

This is a trick question where a lot of data has been given.

The only data we need is the Scale of X axis.

1 km is represented by 2 cm

$∴$ 12 kms are represented by : $\frac{12}{2}$ = 6 cms. which is the X - Coordinate
