At 3:00pm two cars are 345 miles apart & are travelling towards each other.?

Question

If one car is travelling at 55mph and the other at 60mph, at what time will they meet?

Answer 1

The two cars are approaching each other at a total rate of 115 miles an hour. So in 3 hours (345/115), they will meet in a spectacular crash!

Tell the authorities to meet you at the crash site at 6:00pm.

You could do this using algebraic equations as follows:
Let T = time in hours that each car travels

Add the distance that each will travel; it will add up to 345 miles:
60T + 55T = 345

Factor out the common T:
(60 + 55)T = 345

Add 60 + 55:
115T = 345

Divide both sides by 115:
T = 345 / 115
T = 3 hours

So they speed toward each other for 3 hours. Since they started at 3:00pm, that means they will meet at 6:00pm. (And despite what I said earlier, I hope they don't crash into each other.)

Answer 2

rate*time=distance

look at the distance between the two cars. It's decreasing because the cars are driving towards each other.

The rate of decrease is the sum of the speeds of the two cars. So we get the following equation for the time it takes to reduce the distance from 345 to 0

(55 + 60)t = 345

now solve for t:
115t = 345
t = 3
since the rate is in mph, they will meet in 3 hours which if they start at 3:00 pm, they will meet at 6:00 pm

Answer 3

6:00
add the speed of the two cars together. thats how many miles go by in an hour. 60 +55= 115
total miles devided by mph. 345 divided by 115=3 3 o clock plus three hours is 6:00

Answer 4

They are closing at 60=55=115 miles/hr
345mi/115mi/hr=3hrs
so the will meet at 6:00 PM

Answer 5

They will meet at 6:00 pm

Answer 6

8 pm india time buyea!
