Answer 1

Answer:

a) 3.6 km/h

b) 144 km/h

c) 20.833 m/s

Explanation:

a) 1 min= 1/60 hour as 1 hour=60 min

1 m=1/1000 km

so 1 m/min = 1/1000÷1/60=60/1000 km/hour

so 60 m/min = 60×60/1000=3.6 km/hour

b)1 s= 1/3600 hour as 1 hour=3600 s

1 m=1/1000 km

so 1 m/s = 1/1000÷1/3600=3600/1000 km/hour

so 40m/s = 40×3600/1000=144 km/hour

c) 1 hour=3600 s

1 km=1000 m

so 1 km/h = 1000/3600

so 75km/h = 75×1000/3600 =20.833 km/hour
