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:
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 ..
Answer:
-72
Step-by-step explanation:
P = 6
Q = 15
How to solve:
Note the equal sign. This means that both expression's out come must equal each other. For that to happen, everything inside both expressions must equal each other. In this case:
6x + Q = Px + 15; 6x + 15 = 6x + 15

Answer:
32x-435
Step-by-step explanation:
(35x-410) - (3x+25)
35x-3x=32x
-410-25=-435
67.3 repeating. You multiply 68 times 50, subtract 82 and 86, them divide by 48. If that doesn't work, try dividing by 50. That should work.
