Answer:
96 minutes or 1 3/5 hours
Step-by-step explanation:
To get this answer properly , we shall be converting any of the time fraction to minutes
The total time taken is 3 4/5 hours
1 hour is 60 minutes, 3 hours is 3 * 60 = 180 minutes
4/5 hours is 4/5 * 60 = 48 minutes
Total travel time is 48 + 180 = 228 minutes
Walking, he did for 2/5 hours = 2/5 * 60 = 24 minutes
Riding on a train took 1 4/5 hours; that would be 60 minutes plus 4/5 * 60 = 48 minutes ; a total time of 108 minutes
Time spent on walking and on train would be 108 minutes + 24 minutes = 132 minutes
The time spent on train would thus be 228 - 132 = 96 minutes = 60 + 36 minutes = 1 hour + 36/60 = 1 hour + 3/5 hours = 1 3/5 hours was spent on the train

Apply quotient power rule
Answer:
1/32
Step-by-step explanation:
You plug 7 for n and solve in calculator.
Given:
a varies jointly as b and c.
a=6 when b=2 and a=3.
To find:
The variation constant and the equation of variation.
Solution:
a varies jointly as b and c.
...(i)
Where, k is the constant of proportionality.
a=6 when b=2 and a=3.
The value of k is 1.
Putting k=1 in (i), we get
Therefore, the variation constant is 1 and the equation of variation is .
