What is n x 567 =
457 + ae
wgv - 48765

n x 567= 567n

457+ae= 457 + ae

wgv- 48765= wgv- 48765

Step-by-step explanation:

The last 2 are the same. Since they are not like terms, they can neither be added nor subtracted. Only like can be added or subtracted

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
