t
'.
If Ravi travels at a speed of
5
km
∕
hr
, time taken is
t
+
10
60
If Ravi travels at a speed of
6
km
∕
hr
, time taken is
t
−
4
60
Distance
=
speed*time
=
P
=
5
(
t
+
10
60
)
=
6
(
t
−
4
60
)
5
(
t
+
10
60
)
=
6
(
t
−
4
60
)
5
t
+
50
60
=
6
t
−
24
60
t
=
74
60
Distance
(
P
)
=
5
(
74
60
+
10
60
)
=
5
(
84
60
)
=
7
km
Therefore, statement I is incorrect.
Statement II:
Let the speed of Babita be
3
x
.
The speed of Amit is
7
x
.
B covers distance
y
.
In the same time, A should cover
80
+
y
.
y
3
x
=
80
+
y
7
x
7
y
=
240
+

y
4
y
=
240
y
=

Total distance
=

+
60
=
140
m
Therefore, statement II is correct.
The answer is option D.
