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 of the path left to cycle. if dina's cycling speed is 10 km/h, how much time longer will masha need to complete the path?

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:

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:

So we know the time and distance:

Now,

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

As we know the speed and remaining distance

Masha needs 0.5 hour to complete the track ..

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

the answer is a
