70,000+3,000
is the expanded form of 73,000

-28-(-24)=-4
14-18=-4
28-32=-4
Any of these should work and there are plenty more that would work as well
The Answer:
36/121
(6/11)^2 = 6/11 multiplied by itself two times
6/11 x 6/11
Numerator: 6 x 6 = 36
Denominator: 11 x 11 = 121
So the answer is 36/121
Hope it helped!
This uses the formula d = r * t
First group
========
This group determines the time to be used by both groups.
t = d/r
t = 24 / 6
t = 4 hours hours going there.
t = 24 / 4
t = 6 hours
Total time taken is 6 hours + 4 hours = 10 hours.
Group two
========
t = 10 hours.
d = 48 miles (remember, they have to come back).
r = 48 miles / 10 hours
r = 4.8 miles / hour
For humans, that actually is quite quick.
