Step-by-step explanation:

Given :-

Distance cover in 50 minutes - 1.5 km

speed in m/s - ?

km - m

1.5 ÷ 1000 = 1500

1500 m

50 minutes - ? second

1 minute - 60 second

2

So the answer is

m/s - 1500/ 3000 OR 1/2

Answer 2

Answer:

His speed is 0.5 m/s

Step-by-step explanation:

Given, a man covers a distance of 1.5 km in 50 minutes

1.5km = 1500m

50 minutes = 50×60 sec = 3000 s

Distance = 1500 m

Time = 3000 s

We know speed = distance/time

                 = 1500/3000 m/s

                 = 0.5 m/s
