Question

A man can walk 8 km in 1 hour 15 minutes.find his speed.

Answer 1

we know that speed = distance/time

given

distance = 8km , time = 1hour 15min

                                    = 1 + 15/60 (to convert minute into hour)

                                    = 1 + 1/4

                                    = 4 + 1/4 (taking LCM)

                                    = 5/4

speed = 8/5/4

          = 8 x 4/5

          = 32/5

          = 6.4 km/hr

HOPE THIS HELPS !!

 

Answer 2

Hey dear

here is your answer

Distance = 8km

Time = 1 hour 15 minutes = 5/4

Speed = distance x speed

= 8 x 4/5

= 32 km per 5 hour

= 6.4 km / hour
