Can somebody pls help? ​

Answer»

Step-by-step explanation:

1) assume marks in maths is x and marks in science is y

then you will get TWO linear equation with two VARIABLES from data. from where you can FIND x, y.

2) let's assume that train travels distance of (d) in time (t)

the speed = distance/time

360 = d/t

365 = d/(t - 1)

eliminate d from both eqn and find t

actually your question MUST be to find time taken by train at speed of 360km/hr to COMPLETE distance d
