Answer:
Step-by-step explanation:
- Speed = Distance/Time
- => Speed = 15 km ÷ 13/60
- => Speed = 15 km ÷ 0.216
- => Speed = 15 km/0.216
- => Speed = 15 x 4.63/0.216 x 4.63
- => Speed = 69.45 km/1 h (Approximate)
<u>Conclusion:</u>
- Therefore, the speed is 69.45 km/h (Approximate)
Hoped this helped.
Answer:
29°
Step-by-step explanation:
Angles 1 and 8 are alternate exterior angles where a transversal crosses parallel lines, so are congruent.
m∠1 = m∠8
3x+25 = 4x-17
42 = m . . . . . . . . add 17-3x
Then the measure of ∠1 is 3·42 +25 = 151 (degrees), and the measure of its supplement, ∠2 is ...
m∠2 = 180° -151° = 29°
Answer:
Step-by-step explanation:
Don't know. Maybe you add up the two numbers then divide the answer.
Answer:
average speed = distance / time
60 = distance / (13.20 - 10.40)
13.20 - 10.40 = 2 hours 40 minutes = 2 2/3 hours
60 = distance / 8/3 = 3 d / 8 (where d = distance)
3d = 480
d = 480/3 = 160 miles
It should be A and D, no promises
