Example Step by Step
A ball was thrown off a bridge. The table relates the height of the ball above the ground in
feet to the time in seconds after it was thrown. Use the data to enter a quadratic model in
vertex form and convert it to standard form. Use the model to find the height of the ball at
3.5 seconds.

answer: no

step-by-step explanation:

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.
