Answer & Explanation 1.(e); Distance covered by car=8 X 10=800 km Speed=800/8=100 kmph Required Speed=100-80=20 kmph 2.(c); Distance=300 Required speed=(4/5) X 5 = 4 hr So, Required Speed=500/4 = 75 kmph. 3.(b); C covered the journey in 42 min. B covered the journey in 14 min. So, A covered the same journey in 7 min. 4.(e); Required time=(4/5) X 25=20 hr Required Speed= 300/20 = 15 kmph 5.(a); Required time=180/(60+20) = 2 hr So, meeting point of two train=60 X 2=120 km 6.(c) 7.(c); Let distance be x x/(3+1) + x/(3-1) = 45/60 (x+2x)/4 = 3/4 x=1 km. 8.(b);Let distance be x and speed of stream be y. 2x/(6+y) = x/(6-y) 6+y=12-2y 3y=6 y=2 kmph 9.(b); Required distance= 2[1+ 2/3 + (2/3)^2+………………]
=2 X [1/(1- 2/3)]=2 X 3=6 10.(c)
1.(e); Distance covered by car=8 X 10=800 km
Required Speed=100-80=20 kmph
Required speed=(4/5) X 5 = 4 hr
So, Required Speed=500/4 = 75 kmph.
3.(b); C covered the journey in 42 min.
B covered the journey in 14 min.
So, A covered the same journey in 7 min.
4.(e); Required time=(4/5) X 25=20 hr
Required Speed= 300/20 = 15 kmph
5.(a); Required time=180/(60+20) = 2 hr
So, meeting point of two train=60 X 2=120 km
7.(c); Let distance be x
x/(3+1) + x/(3-1) = 45/60
(x+2x)/4 = 3/4
8.(b);Let distance be x and speed of stream be y.
2x/(6+y) = x/(6-y)
9.(b); Required distance= 2[1+ 2/3 + (2/3)^2+………………]
=2 X [1/(1- 2/3)]=2 X 3=6
