Two trains leave two different stations 300 km apart; the first starts at noon and the second at 12 15 h. Travelling on parallel

alexgriva [62]

Answer:

See below

Step-by-step explanation:

From noon to 1500 is three hours

train A then travels <u> 3x</u> where x = speed in km/hr

train B only travels for 2.45 hours and covers

<u> 2.45 ( x + 15) </u> where x + 15 is its speed in km/hr

these two values sum to the 300 km distance

3x + 2.45 ( x + 15) = 300

3x + 2.45 x + 36.75 = 300

x = 48.3 km/hr x+15= 63.3 km / hr
