Answer:
The answer is (D) ⇒ AE ≅ CE
Step-by-step explanation:
∵ <em>ABCD is a parallelogram</em>
∴ AB = DC , AB // DC
∴ BC = AD , BC // AD
∴ m∠A = m∠C , m∠B = m∠D
∴ AC and BD bisect each other at E
∴ AE = CE
∴ The right statement is D ⇒ AE ≅ CE
Time Distance Distance / Time
2hrs 90 miles 90 miles / 2 hrs = 45 miles / hr
3hrs 135 miles 135 miles / 3 hrs = 45 miles / hr
5hrs 225 miles 225 miles / 5 hrs = 45 miles / hr
6hrs 270 miles 270 miles / 6 hrs = 45 miles / hr
Constant of proportionality is 45 miles / hr. This is the same for the four values. The unit rate is also 45 miles / hr.
Let us assume the Distance , d is directly proportional to Time, t
d α t
d = kt
Constant of proportionality is k which is D/T
d = 45t
2m+3=23
2m=20
m=10
