Answer:
25m/sec
Explanation:
Speed of car in first 15 minutes = 40 km/h
Distance covered = speed × Time taken
60 minutes = 1 hour
15 minutes =
60
15
hour
Distance covered = 240×
60
15
=10km
Speed of car in next 15 minutes = 60 km/h
Distance covered = 60×
60
15
=15km
∴ Total distance covered = (10+15)km = 25 km
Answer:
Crest is the highest point that a wave reaches and… Trough the lowest point that a wave reaches............Transverse waves are waves whose particles vibrate at right angles to the direction of wave travel e.g water wave. .....,.......longitudinal I think it's not "longitudin" are waves whose particles vibrate in a direction parallel to the direction of wave travel e.g sound wave
We don't know if the road is perfectly straight between the intersections, or if the road bends, curves, or turns between them. So we don't have enough information to calculate the displacement between them.
But we <em>can</em> calculate the <u>distance</u> the car traveled between them.
Distance = (speed) (time)
Distance = (20 m/s) (120 s)
<em>Distance = 2,400 meters</em>
