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 :
Hence, this is the required solution.
If you would like to solve the equation x/m - x/n = 1/p for x, you can do this using the following steps:
x/m - x/n = 1/p
x * (1/m - 1/n) = 1/p
x = 1/p / (1/m - 1/n)/1
x = 1/p * 1/(1/m - 1/n)
x = 1/(p*(1/m - 1/n))
The correct result would be x = 1/(p*(1/m - 1/n)).
