Question

What is the speed of a walking person if the person travels 750 m in 50 minutes?

Answer 1

Answer:

900m/hr or 0.9km/hr

Step-by-step explanation:

speed = distance/time

distance =750m

time=50 minutes

in 1 minute he travels 750/50=15m

15*60=900m per hour 60 minutes

Answer 2

Answer:

750m = 0.75km

50 mins = 50*60 = 3000 sec

Also, 50min = 80/60 = 5/6 hr

Speed:

1. In m/s = 750/3000 = 0.25 m/s

2. In Km/hr = 0.75/(5/6) = (6*0.75)/5 = 4.5/5 = 0.9 km/hr
