Pat t2 = 40 hrs
Step-by-step explanation:
Given:-
- Fred can paint a house in t1 = 10 hours.
- Pat can paint a house in t2 hours.
- pat and Fred can paint a house in T = 8 hours.
Find:-
Which equation, when solved will produce the number of hours need for pat to paint the house alone
Solution:-
- The number of people working on a particular activity " painting a house " is inversely proportional to time taken to complete the activity. tn = T. The relation for individual time taken ti to complete an activity.
Sum ( 1 / ti ) = 1 / T
Where, ti = The individual time for (ith) person
T = The total time taken to complete the time by i = n number of people.
- For n = 2,
1/t1 + 1/t2 = 1/T
1/10 + 1/t2 = 1/8
1 / t2 = 0.025
t2 = 40 hrs
- It takes Pat t2 = 40 hrs to complete painting the house.
Answer:
The complex numbers have opposite real numbers.
Answer:
t= 0.8 hr or 48 min.
Step-by-step explanation:
Speed of Enrique= 6 mph
Half and hour late it means that after 1/2 hr.
Speed of Enrique brother = 8 mph
Lets take Enrique cover x distance in time t hr .
So
x = 6 t ------------ 1
Then his brother will cover x/2 distance in time (t-1/2) hr.
So
x/2 = 8 (t-1/2) -----------------2
Now from equation 1 and 2
6 t = 16 (t-1/2)
6 t = 16 t - 8
So t= 0.8 hr or 48 min.
It means that his brother will take 0.8 hr to cover half of distance cover by Enrique .
