4 / 1 = 1 / x....4 miles to 1 hr = 1 miles = x hrs
cross multiply
4x = 1
x = 1/4.....it would take 1/4 of an hr (or 15 minutes) to walk 1 mile
The actual length :
26.8 * 0.5 = 13.4 meters
The actual width :
12.2 * 0.5 = 6.1 meters
The actual area of the court:
13.4 * 6.1 = 81.74 meters square
Hope that helps you
d) Alternate interior angle to angle 3 is angle 6.
e) Alternate exterior angle of angle 7 is angle 2
Your answer would most likely be
B
D=vt
So they will travel downstream and upstream the same distance. Downstream they will travel:
d=(2+18)t1
Upstream they will travel:
u=(18-2)t2
Since d=u we can say:
20t1=16t2
We are told the trip lasts 3 hours so t1+t2=3, t2=3-t1, using this in the equation above we have:
20t1=16(3-t1)
20t1=48-16t1
36t1=48
t1=4/3 hours, and from earlier we saw that d=20t1 so:
d=20*4/3
d=80/3 miles
d=26 2/3 miles.
