A bullet train leaves Kyoto for Tokyo traveling 240 miles per hour at 12 noon. Ten
minutes later, a train leaves Tokyo for Kyoto traveling 160 miles per hour. If Tokyo and
Kyoto are 300 miles apart, at what time will the trains pass each other?

12:55
0 13:00​

Answer 1

Answer:

12:49

Step-by-step explanation:

Train A: going from K to T

Train B: going from T to K

First I calculated how far Train A will have travelled by the time Train B starts at 12:10:

10 minutes at 240 mph

1/6*240=40miles

They have 300-40=260 miles to travel to meet each other.

I found the combined rate of the two trains

Rate(A) + Rate(B) = 400mph

Divide Distance/Rate to find total time each will travel:

260/400=39/60 >>> 39 Minutes to meet

12:10+39 minutes = 12:49 or Answer B

Thank you.....
