Question

Determine the speed in either km/h or m/s.
(a) Distance= 1500 km Time = 20 hours
(b) Distance= 13350 km Time = 25 hours
(c) Distance = 9000 m Time = 50 minutes
(d) Distance = 2500 km Time = 1 hour 40 minutes
(e) Distance = 100 m Time = 2 minutes 5 seconds​

Answer 1

Step-by-step explanation:

1 km = 1000 m

Or

1 m = 1/1000 km

1 hour = 60 minutes

Or

1 minute = 1/60 hrs

1 minute = 60 seconds

Or

1 second = 1/60 minutes

Answer 2

Step-by-step explanation:

speed = distance / time

a) speed = 1500 km / 20 hr

= 75 km/hr

b) speed = 13350 km / 25 hr

=534 km / hr

here 9000 m = 9 km and 50 minutes = 5/6 hr

c) speed = 9 km / 5/6 hr

54/5 = 10.80 km/hr

d) 1 hour 40 minutes = 5/3 hr

speed = 2500 / 5/3

= 7500 / 5 = 1500 km/hr

e) 2 minutes 5 seconds = 125 seconds

speed = 100 / 125 = 4/5 = 0.8 m/s
