irga5000 [103]
Percent decrease = (change in value) / (original value)

change in value = 9965-10100 =-135

original value = 10100

Look Down Below For question:
Ray Of Light [21]
The cattle train
speed - 36.5 km/h
time - x h

the passenger train
speed - 29.2 km/h
time - (2.4+x) h

The cattle train caught up to the passenger train so the distance they travelled is the same.
Distance is speed times time.

36.5 \times x=29.2 \times (2.4+x) \\&#10;36.5x=70.08+29.2x \\&#10;36.5x-29.2x=70.08 \\&#10;7.3x=70.08 \\&#10;x=\frac{70.08}{7.3} \\&#10;x=9.6 \\ \\ 2.4+x=2.4+9.6=12

The passenger train travelled for 12 hours before the cattle train caught up.
