Question

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.after how long will they be 580 km apart​

Answer 1

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.

Answer 2

Correct Question

two cars start from the same place at the same time but in opposite directions their speeds 80km/h after how long will they be 580 km apart

Given :-

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.

To Find :-

How  long will they be 580 km apart​

Solution :-

We know that

Distance = Time × Speed

580 = Time × 2(80)

580 = Time × 160

580/160 = Time

3.63 = Time

or

3 hrs. 38 min
