Aptitude Test Questions with Answers for SSC Exam

Let 6 speed cover in x minute time

So that 5 speed cover in (x-10) minute time

So we can say 

6x=5(x-10)

x=50 minute

First of all we convert unit in meter/sec             

5 minute=5×60sec

Let the original speed of car is x km/hr. then,

Due to stoppages, it covers 9 km less.

Time taken to cover 9 km  =  min=10 min.

A walks in 4 hour is 4✖4 =16 km 

After B start D=Speed×Time

16=6T

T=16/6

Then Distance covered by B is

D=ST

Suppose the thief has overtaken x hrs after 2.30 P.M.

Then, distance covered by the thief in x hours=distance covered by the owner in (x-1/2) hrs

so the thief is overtaken at 5 p.m.

Distance=990 km

Train   Car
3          1
Speed of car is =520/8=65km/h
so that speed of train = 65*3=195 km/hour
Distance covered by train=speed*time=195*13=2535 km
