Answer:
7
Step-by-step explanation:
The equation of direction variation is
y = kx where k is the constant of variation
y = 7x so 7 is the constant of variation
Speed= distance/time
Therefore, time= distance/speed.
Plug in the known values
t= 175/25
t= 7
Final answer: 7 hrs
Answer:
C. 1/2
Step-by-step explanation:
Since there is 1 drummer and 2 singers, the ratio is 1 to 2.
Yesterday's time: t = 2 hr 20 min
Today's time: 0.73(2 hr 20 min) = 0.73 (2.333 hr) = 1.703 hr
This can be expressed in hours and minutes:
60 min
1 hr + 0.703 hr = 1 hr + 0.703 hr * --------------
1 hr
= 1 hr + 42.18 min
Rounded off to the nearest minute, we get 1 hr 42 min (answer)
