Let the number be x
176 = 4/6 * x
4/6*x = 176
4x = 176 *6
x = 176 * 6 /4 Use your calculator.
x = 264
Therefore the number = 264
Answer:
18 hours
Step-by-step explanation:
The answer is 18 hours. We know 8 is a factor of 48, so we do 3/8 times 6/6 and get 18/48. So there is 18 1/48 in that fraction, so it will take them 18 hrs.
Speeds are s_c for car, s_m for motorcycle.
time is 2
distance of car is:
d_c = d_m + 20, d_m is distance of motorcycle.
speed is defined as:
s = d/t, distance over time.
hence:
d_c/2 = s_c = d_m/2 + 10
s_c = s_m + 10
from problem statement we know:
s_c = 2s_m - 30
so we have 2 simultaneous equations:
<span>s_c = s_m + 10
</span><span>s_c = 2s_m - 30
</span>
multiply second by -1 and sum them both:
<span> s_c = s_m + 10
</span>-s_c = -2s_m + 30
-------------------------
0 = -s_m + 40
s_m = 40
that is the speed of the motorcycle
s_c = <span>s_m + 10
</span> s_c = 40<span> + 10
</span>s_c = 50
that is the speed of car, both speeds in miles per hour
Answer:
