Aptitude - Time and Distance - Discussion

Hi Abhi & Shika,



Kindly go through the basic formulas for solving Time and Distance problems.



Have a nice day!

Hi Vidu and Sushree,

You questions is from where did 60 come?

Please concentrate on the unit name mentioned along with the numbers.

Speed = Distance/Time

Here Distance = 600 meters and Time = 5 mins.

Therefore, Speed = 600/5 meters/minutes.

We have to write it as in terms of meters/seconds. So we are multiplying it with 60 (1 min = 60 seconds).

So, Speed = 600/(5 x 60 sec) meters/seconds.

I strongly suggest all newbies to go through the basic formulas before posting your doubts here. So, kindly go through the basic formulas for solving Time and Distance problems.

Have a nice day!

@jayan,jashwa
to convert km/hr to m/sec, we hav to do in dis way.....
1km=1000m
1hr=3600sec
1km/hr=1000/3600 m/sec
therefore 1km/hr=5/18 m/sec


similarly to convert m/sec, we hav to in reverse way.....
1000m=1km ---> m=1/1000km
3600sec=1hr ---> sec=1/3600hr
its just a normal cross multiplication
m/sec=3600/1000 km/hr
therefore m/sec=18/5 km/hr

its not necessary to do al these steps. i included al the steps just for your better understanding......... hope u can understand now

thank u

The speed formula= distance/time.

So we have speed=600 metres/ 5 min
In this 5 is a minute value so we have to convert it into seconds
Because metres/seconds is a current formula
so we need to change the 5 min value into seconds
1 min= 60 seconds.
So 5 min = 5*60.
= 300 sec that's why 60 will come in this section
now we calculate speed = 600/300 m/sec.
= 2 m/sec

On step 2:
we need the man speed in km/hour.
so we need to convert m/sec into km/hour.
using 1000/3600= 5/18.
Because 1 km= 1000 m.
and 1 hour= 3600 sec ( 1min= 60 sec then 1hour= 60 min so 60*60= 3600 sec)
the answer is 2*5/18= 7.2 km/hour.

I don't get it. Please explain in detail.

Thanks all for explaining the answer.

Where we got 60 there?

From where the 60 came?

Forget this above mentioned method

one man cover 600 m in 5 min thn in 60 min (1 hour)how much he cover

( 60 x 600 ) / 5 = 7200 m = 7200 / 1000 = 7.2 km / hour

1 km = 1000 m

600/5=120/min,
1min=120m,
60min=60*120m=7200,
1000m=1km.
So, 7200m/1000m=7.2/hr.
