Answers
Answer:
They will be 580 km apart in 3 hours and 37.5 minutes.
Step-by-step explanation:
Given that:
Two cars start from the same place at the same time but in opposite directions, both cars travel at a speed of 80 km/hr.
So,
After 1 hour, They will be 160 km apart.
To Find:
How long will they be 580 km apart?
We know that:
≛ Time = Distance/Time ≛
We have:
Distance = 580 km
Speed = 160 km per hour
⇢ Time = 580/160 h
⇢ Time = 3.625 h
Converting time in hours and minutes:
≛ 1 h = 60 min ≛
3.625 h = 3 h + (60 × 0.625) min
3.625 h = 3 h + 37.5 min
3.625 h = 3 h and 37.5 min
Hence,
After 3 hours and 37.5 minutes, they will be 580 km apart.
