Is Known from the question

• mileage (S )= 400 Km
• time (t )= 3,5 hours

Asked

Speed in Km/h =?

V = s/t

V = 400 km/ 3,5 hours

V= 114,2 km/h

speed in m/s ?

V = s/t

V = 400.000 m /12.600 S

V = 31 ,74 m/s

So, speed of the car in Km/h is 114,2 Km/h , and the speed of the car in m/s is 31 ,74 m/s

_______________

pembuktian

a. V = s/t

114,2 = 400/t

114,2 t = 400

t = 3,50 h

terbukti

b. V = s/t

31,74 = 400.000 /t

t = 12.600 s
