A northbound train and a southbound train meet each other on parallel tracks heading in opposite directions. The northbound trai

SSSSS [86.1K]

Answer:

50mph,60mph

Explanation:

Let speed of southbound train=x mph

Speed of northbound train,y=x+16 mph

Distance between two trains after 1.5 hour,174 miles.

We have to find the speed of two trains.

Distance= $speed\times time$

Using the formula

$174=1.5x+1.5(x+16)$

$174=1.5(x+x+16)$

$174=(2x+16)\times 1.5$

$174=3x+24$

$3x=174-24=150$

$x=\frac{150}{3}=50mph$

$y=x+16=50+16=66mph$
