Two steamers leave a port on a river at the same time, traveling in opposite directions. Each is traveling 22 mph. How long will
vivado [14]

It took both  2.5 hours to be 110 miles apart

Speed is the ratio of distance travelled to time taken. Speed is given by:

Speed = distance / time

Since both steamers is travelling at 22 mph. therefore they cover the same distance at the same time. For them to be 110 miles apart, they need to each have covered 55 miles in the opposite direction

22 = 55/time

time = 2.5 hours

Therefore after 2.5 hours they would have covered 55 miles each therefore being 110 miles apart.

There are 10 red and 20 yellow balls. Drawing 3 balls without replacement, what is the chance the first is red and the next two
Xelga [282]

10 + 20 = 30 total balls.

Picking red = 10/30 = 1/3

After picking one ball there are 29 balls left.

Picking a yellow next is 20/29

Then there are 28 balls left and 19 yellow left, so picking another yellow would be 19/28

The probability of picking red first then two yellow = 1/3 x 20/29 x 19/28 = 95/609
