Time Distance and Speed
A train can travel 20% faster than a car. Both start from point A at the same time and reach point B 80 kms away from A at the same time. On the way, however, the train lost about 32 minutes while stopping at the stations. The speed of the car is:
A)30 kmph B)40 kmph C)25 kmph D)50 kmph
Read Solution (Total 2)
-
- d=80
car speed =s1
train speed s2=1.2*s1
time diff=32/60
80/s1 - 80/1.2s1 = 32/60
s1=25kmph - 3 years agoHelpfull: Yes(1) No(0)
- distance =80km
speed of a car = x kmph
the speed of a train =(120/100)x kmph=1.2x kmph
time diff is 32min
now,
80/x-80/1.2x=32/60
80[1/x-1/1.2x]=32/60
x=25kmph
hence the speed of the car is 25kmph - 3 years agoHelpfull: Yes(0) No(0)
