A bus drives for 3 1/2 hours at an average speed of 56mph.
How far does the bus drive?

196 km

Step-by-step explanation:

Distance = speed x time

So to work it out, it would be 3.5 x 56

= 196km

A bus drives for 3 1/2 hours at an average speed of 56mph.

To Find :

How far does the bus drive?

Step-by-step explanation:

Times of journey(T)=3 1/2 =7/2hours

Average speed of bus(v)=56mph

We know the formula:

Average speed (v)=total distance (d)/Time(T)

So:

Total distance (d)=qverage speed(v)×time(t)

Total distance (d)=56×7/2

Total distance(d)=28×7=196 miles

It means distance travel by bus is 196 miles.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
