Don leaves home at 2 pm.
1 answer:
Answer:
Please find the attached traced distance time graph
Step-by-step explanation:
The given parameters are;
The time at the start of Don's journey = 2 pm.
The distance Don drives one hour after leaving home = 45 miles
The speed (Distance/time) Don drove during that time = 45/1 = 45 mph
The time at which Don first stop driving = 2 pm + 1 hour = 3 pm
Don then stops for 90 minutes
The time after the duration at which Don stops driving = 3 pm + 90 minutes = 3 pm + 1.5 hours = 4.30 pm
At 4.30 pm. Don then starts driving home at 15 mph
The distance from Don's home from where Don stopped is 45 miles, therefore;
Time (Distance/speed) for Don to get home = 45 miles/15 mph = 3 hours
Time Don arrived home = 4.30 pm + 3 hour = 7.30 pm.

Answer: No; they do not have proportional corresponding sides
Step-by-step explanation:
Since, here in triangles GHI and JKL,
∠ G = 46°, ∠I = 27° ⇒ ∠H = 107° , ∠L = 27°, ∠ K = 108°⇒∠J = 45°
GH = 4, HI = 5 , KJ= 2 and JL = 4
Here ∠I ≅ ∠L
But,
Therefore, they do not have proportional corresponding sides.
That is why they are not similar to each other.
