Just divide the distance by the time.
To know the velocity, you would also need to know in what direction the car travels.
Since the equation for time=sqrt(2h/g) set 2 seconds for time and 9.8 for gravity so 2=sqrt(2h/9.8) clear the sqrt by squaring both sides 4= 2h/9.8 9.8*4 =2h (9.8*4)/2 = height. now that you have the height, you can do v=distance/time v=height from the equation prior/2 seconds i hope that works..
To find the speed, take the distance and divide it by the time. 100m/2h = 50m/hr
a cubic trinomial is when there is 3 symbols such as a+b+c+2h there are 3 different symbols for the equation just the same as a*b-3h+2h there is a *,-,+ in that equation making there be 3 making it a cubic trinomial
2H
The hardest lead in drawing pencils is 2H or 4H.
Ave speed = Distance/Time = 120 km / 2 hours = 120/2 km per hour or 60 km per hour.
40km/hr
2h + 2h + 2h = 6h
2h by car 1,5h by train 45min by air
1d 2h 23m
2 hours and 7 minutes (1h = 60 minutes so 2h = 120 min)
speed = distance/time = 100mi/2h = 50mi/h
2h means two handed
2h 32mins if you travel by car via M1 (128km).
2h by car 1,5h by train 45m by air
speed = 80km/2h = 40km/h
Factor 2h−2 2h−2 =2(h−1) Answer: 2(h−1)
