Find the value of g in the figure given below.
Assume that the lines are parallel.

d=60-degree (Vertically opposite angles)

e=d=60-degree (Alternate angles)

e+g=180-degree (Being in a straight line)

60+g=180

g=180-60

g=120-degree

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.
