Dina and Masha start cycling on a 20 km bike path at the same time. When Dina reaches the end of the path, Masha still has 4 km

sammy [17]

Answer:

0.5 hour

Step-by-step explanation:

Given

Speed of Dina = 10 km/h

Distance = 20 km

So the time Dina taken to complete the track is:

$Speed=\frac{distance}{time}\\10=\frac{20}{time}\\time=\frac{20}{10}\\ time=2\ hours$

The time taken by Dina is 2 hours. As masha started with dina but she was 4 km of the path left to cycle,

her distance covered in 2 hours was:

$Distance\ covered\ by\ Masha\ in\ 2\ hours=20-4\\=16 km$

So we know the time and distance:

Now,

$Speed\ of\ Masha=\frac{distance}{time}\\ =\frac{16}{2}\\ =8\ kilometer\ per\ hour$

We have to calculate the time that will be needed by MAsha to complete the track:

As we know the speed and remaining distance

$Speed=\frac{distance}{time}\\8=\frac{4}{time}\\ time=\frac{4}{8}\\time=0.5\ hours$

Masha needs 0.5 hour to complete the track ..

An algebra class has 21 students who all participate in a welcome activity introducing themselves to each other in pairs. One st

Nuetrik [128]

The handshake is an illustration of combination, and the values of n and r are 21 and 2, respectively

<h3>How to determine the values of n and r?</h3>

The number of students in the class is 21.

This represents the value of n

i.e. n = 21

Each student shakes hand with another student (i.e. 2 students per handshake)

This represents the value of r

i.e. r = 2

Hence, the values of n and r are 21 and 2, respectively
