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:
I = 2,340
Step-by-step explanation:
The formula for interest is
I = P × R × T / 100
P = $5200
R = 15%
T= 36 months; T is meant to be in years so we will convert it from months to years
1 year = 12 months
So 36 months
= 36 /12 = 3 years
I = (5200 × 15 × 3)/100
I = 234,000 / 100
I = 2,340
