✔ 最佳答案
The difference in rates is 1 km/hr. So if they are moving in the same direction, the faster walker will be 5 km ahead at the end of 5 hours.The sum of the distances traveled per hour is 11 km. So at the end of 5 hours of travel in opposite directions, they will be 55 km apart.

5 km and 55km
5*5=25
5*6=30
same 30-25=5
opposite 30+25=55
5*5=25
5*6=30
same 30-25=5
opposite 30+25=55

5 km and 55 km
In same direction, the distance is: (6-5) x 5 = 5 km
In opp. direction, the distance is (6+5) x 5 = 55
In same direction, the distance is: (6-5) x 5 = 5 km
In opp. direction, the distance is (6+5) x 5 = 55

5km/h; Distance covered in 5 hours = 5*5 = 25km
6km/h; Distance covered in 5 hours = 6*5 = 30km
So if they are moving in the same direction, they would be 30-25=5km apart.
If they are moving in the opposite direction, they would be 30+23=55km apart.
6km/h; Distance covered in 5 hours = 6*5 = 30km
So if they are moving in the same direction, they would be 30-25=5km apart.
If they are moving in the opposite direction, they would be 30+23=55km apart.

for opposite direction distance= 5*5+6*5
for same direction distance= 6*5-5*5
(do rest of the multiplication and addision stuffs urself)
for same direction distance= 6*5-5*5

In same direction from the same point (6*5)- (5*5) = 5km apart
Opposite direction from the same point (5*5)+(6*5) = 55 km
Opposite direction from the same point (5*5)+(6*5) = 55 km

suppose the two person walk for 5 h without exhaution or tiring ( like amachine)
the distance between them after 5 h in the same direction = 5 km
and in opposite direction = 55 km
the distance between them after 5 h in the same direction = 5 km
and in opposite direction = 55 km

lots of correct answer, ty

The distance between the two persons while walking in the same direction is going to be 5 kms and 55 kms when walking in the opposite direction.

Their speed=
person A's distance travelled will be= D=SXT
so the distance travelled will be 5X5= 25 km
person B's distance travelled=
6X5= 30 km
so the distance between them in the same direction will be: 30-25= 5 km
distance between them when they travell in opp. direction=
25+30= 55km
person A's distance travelled will be= D=SXT
so the distance travelled will be 5X5= 25 km
person B's distance travelled=
6X5= 30 km
so the distance between them in the same direction will be: 30-25= 5 km
distance between them when they travell in opp. direction=
25+30= 55km

55 km !
2006-05-08 12:28 pm
when moving in same direction distance between them= 5 km.
when moving in opposite direction distance between them=55 km.
when moving in opposite direction distance between them=55 km.
2006-05-08 12:28 pm
If they move in same dir 5*6-5*5=15km
If they move in opp dir 5*6+5*5=55km
If they move in opp dir 5*6+5*5=55km

If they walk in the same direction:
Dist between them = 5hr (6km/hr - 5km/hr)
= 5km
If they walk in opposite directions:
Dist between them = 5hr (6km/hr + 5km/hr)
= 55km
Dist between them = 5hr (6km/hr - 5km/hr)
= 5km
If they walk in opposite directions:
Dist between them = 5hr (6km/hr + 5km/hr)
= 55km
2006-05-08 12:27 pm
same direction:(6x5)-(5x5)=30-25=5km
opposite direction:(6x5)+(5x5)=30+25=55km
opposite direction:(6x5)+(5x5)=30+25=55km
2006-05-08 12:27 pm
if in the same directuon,
(6*5)-(5*5)=1*5=5km
if they move in the opposite direction,
(6*5)+(5*5)=55km
(6*5)-(5*5)=1*5=5km
if they move in the opposite direction,
(6*5)+(5*5)=55km
2006-05-08 12:25 pm
5 km and 55km
5*5=25
5*6=30
same 30-25=5
opposite 30+25=55
5*5=25
5*6=30
same 30-25=5
opposite 30+25=55
