Answer:
m = 1.25d
Step-by-step explanation:
A train is traveling at a constant speed and goes a distance of 7 ½ kilometers or 7.5 km in 6 minutes.
6 min = 7.5 km
1 min = (7.5/6) km/min
= 1.25 km/min
or
In m min, (7.5/6)d is travelled by the train. Hence, the relation between d and is :
[tex]m=\dfrac{7.5d}{6}\\\\m = 1.25d[/tex]
Hence, this is the required solution.
