Question

(ii) A man runs from a place A to a place B in 1 hour 30 minutes. If the distance between
the two places is 6 km, find his speed​

Answer 1

Step-by-step explanation:

15 minute is the right answer

Answer 2

Step-by-step explanation:

the time should be converted into minutes

1h= 60 minutes

hence 60+30= 90minutes

1min =60sec

90min=. 90*60 = 5400sec

1km=1000m

hence 6km= 6*1000

=6000m

speed =distance/time

speed = 6000/5400

=10/9

10/9*18/5= 4km/h

Hence the speed of the man is 4km/hr
