68 miles / hour
Average speed = distance / time
distance = 170 and time = 5/2 ( as an improper fraction)
speed = 170 ÷
= 170 ×
=
= 68
Answer:

Step-by-step explanation:
general slope intercept equation of a straight line is given as

where m is slope and b is y-intercept
here
and

A/b *100
For example,
30/600.
30/600=0.05
0.05*100=5%
Answer:
Choice 1
Step-by-step explanation:
m^2 +n^2=13^2
m^2=13^2-n^2
n^2=13^2-m^2
Both m & n =(13 x sq rt 2)/2
To put it another way:
m=(sq rt 2)/2 x 13
n=(sq rt 2)/2 x 13
