Question

Posted · Report post

Mr.X arrived at his home at 12:00.

If he had traveled 15 km/h faster, he would arrive 1 hour earlier.

If he had traveled 10 km/h slower, he would arrive 1 hour later.

What is his rate, when did he departed and how long (in km) did he traveled?

Please excuse me because of my silliness.

I had misread the problem at another source, it seemed hard to me, as it had endless answers.

The true problem was that:

Erase "faster" and "slower" words. Add "at 15 km/h" and "at 10 km/s".

It became an easy one now, anyway.

Excuse me for annoyance. :blush:

Total distance = 60 Km

If he traveled at 15 Km/h it would have taken 4 hours

If he traveled at 10 Km/h it would have taken him 6 hours

It took him five hours because he traveled at 12 Km/h

He left at 7:00
