treat the mass of the tin and iron nails as separate items...

1/2 = 4/8

Hi pls help


Ali left town A and travelled towards town B at speed of 90km/h.
45min later, Muthu left town B and travelled town A at speed of 120km/h.
Town X was halfway between town A and town B. Ali passed town X half an hour after Muthu had passed town X. Both speeds did not change throughout the journey. If Muthu reached town A at 2.45pm, at what time did Ali leave town A?

Thanks!

Time taken by Ali to travel from A to X = 4 x 75 min = 5h
Total time taken by Ali to travel fro A to X = 10h
10h before 2.45pm --> 4.45am
Ali left at 4.45am

Hi, i'm new here and happen to see this question being posted.

My solution is: We should be finding time taken by Muthu to travel from B to A= 2x3u=450minutes=7.5 hrs

Hence, time Muthu left Town B =7.5hrs before 2.45pm ( being the time Muthu reached town A) =7.15am

Given that Muthu left Town B 45minutes after Ali left Town A, hence time Ali left Town A =6.30am ( 45 minutes before 7.15am )

Please feel free to correct me if am wrong. Thanks a lot!


cheers.
