Find his speed in km/hour.​

Answer 1

Answer:

18km/hr

Step-by-step explanation:

Distance covered in 4 minutes= 1200 m

Distance covered in 1 minute= 1200÷4

= 300m

Distance covered in 60 minutes= 300×60

=18,000m= km

= 18000÷1000=18 km

1200 m = 1.2 km

4 min. = 4/60 hours

speed = dist./time
