Answer:

1224km/hr

Explanation:

To convert from m/s to km/hr

1000m = 1km

Divide both sides by 1000

1m = 1/1000 km................. (1)

60×60 seconds = 1 hr

3600s = 1hr

Divide both sides by 3600

1s = 1/3600 .............(2)

Divide (2) by (1)

1m/s =  1/1000 ÷ 1/3600 km/hr

1m/s = 1/1000 × 3600/1  km/hr

1m/s = 3600/1000  km/hr

1m/s = 3.6 km/hr .............(3)

To convert 340m/s to km/hr

Multiply (3) by 340

1× 340m/s = 3.6 × 340 km/hr

340m/s = 1224km/hr

Answer:

1224 km/hr

Explanation:

Method 1

to convert m/s to km/hr

recall that :

1km = 1000m

firstly lets convert m to km

340 m to km

340 / 1000

= 0.34 km

recall that :

1hr = 60 min

1 min = 60 seconds

hence 1 hr = 60*60

1 hr = 3600 seconds

now to convert seconds to hr :

1 second / 3600

=1/3600 hours

hence to get the answer you say :

[tex]\frac{0.34}{\frac{1}{3600} }[/tex]

= 1224

Method 2

recall : 1km = 1000m

recall: 1hr = 60 min

          1 min = 60 seconds

hence 1 hr = 60*60

1 hr = 3600 seconds

now to get this answer you have to divide m by 1000 to get km

and you have to divide seconds by 3600 to get hours

= [tex]\frac{340 / 1000}{1/3600}[/tex]

= 1224
