Step-by-step explanation:
or, 6m=5/13
or, m=5/13 ×6m
m=30/13
Answer:
The groups walking speed is
or ![1.875\frac{miles}{hour}](https://tex.z-dn.net/?f=1.875%5Cfrac%7Bmiles%7D%7Bhour%7D)
Step-by-step explanation:
we know that
To find the speed divide the distance by the time
so
![\frac{(3/8)}{(1/5)}=\frac{15}{8}\frac{miles}{hour}](https://tex.z-dn.net/?f=%5Cfrac%7B%283%2F8%29%7D%7B%281%2F5%29%7D%3D%5Cfrac%7B15%7D%7B8%7D%5Cfrac%7Bmiles%7D%7Bhour%7D)
Convert to mixed number
![\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\frac{miles}{hour}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B8%7D%3D%5Cfrac%7B8%7D%7B8%7D%2B%5Cfrac%7B7%7D%7B8%7D%3D1%5Cfrac%7B7%7D%7B8%7D%5Cfrac%7Bmiles%7D%7Bhour%7D)
Answer:
x = 3
Hope this helps!
Step-by-step explanation:
ΔABC is a 45°, 45°, 90° triangle. The longest side ( 6
) can be
while AB and CB are x. Because 6
is equal to
, you can see that x is equal to 6. Both AB and CB are equal to 6. ΔBDC ( CDB ) is a right triangle ( 30°, 60°, 90° ) so, BD = x, CB = 2x, and CD =
. CB is equal to 6 so 2x = 6, x = 3.
