3p = 37-13
3p = 24
3p/3 = 24/3
p = 8
Answer:
11th or 16th day
Step-by-step explanation:
8.76 x 10^6 is 10,000 times greater than 8.76 x 10^2.
1.
<span><span>time she spent walking = T
</span><span>
</span></span>
time she spent jogging = 1.2 - T
<span>
<span>
</span></span>
<span><span>2T + 4(1.2 - T) = 3.4
</span><span>
</span></span>
<span><span>2T + 4.8 - 4T = 3.4
</span><span>
</span></span>
<span><span>2T - 4T = 3.4 - 4.8
</span><span>
</span></span>
- 2T = - 1.4
T = -1.4—2 = 0.7 hours = 42 minutes
Time she spent jogging = 1.2-0.7 = 0.5 hours = 30 minutes
2.
Against wind :2400 miles in 10 hours
With wind : 2400 miles in 8 hours
Speed of plane = x
Speed of wind = y
t=d/r
against the wind speed x-y mph
with the wind x=y mph
2400/(x-y)=10
2400 = 10x-10y
240 =x-y eq.1
2400/x+y=8
2400 = 8x+8y
300 = x+y eq 2
Add eq1 & eq 2 = 740 = 2x
X = 740/2 = 370 mph for plane
300 = 370 +y
Y = 370-300 = 70 mph wind speed
