Answer 1

man covered a certain distance at some speed. Had he moved 3 km per hour faster, he would have taken 40 minutes less. If he had moved 2 km per hour slower, he would have taken 40 minutes more. The distance (in km) is:

40.

Answer 2

Answer:

40

Step-by-step explanation:

Distance =S1S2

S1−S2×t

from both conditions,

S(S+3)×40

3

S(S−2)×40

2

2S+6=3S−6

S = 12 km/hr

from condition 1st

12×153×4060 = 40 km
