Solution:</h3>
- In order to multiply fractions, we should multiply the numerator of the first fraction times the numerator of the second fraction, like so:
- 3•5=15
- Do the same with the denominator:
- 10•7=70
- 15/70 is the answer.
- Same with the other fractions:
- 7•2=14
- 10•4=40
- Hence, 14/40 is the answer.

Let s = the speed of the slower train in km/hrs+10 = the speed of the faster train in km/hrLet t = time in hrs for the slower train to go 160 kmt-5 = time in hrs for faster train to go 160 km---------------Slower train:(1)
160=s.t
Faster train:(2) 160=(s+10) .(t-.5)From (1)(1) t=160/s
use the relations given in following screenshot and then use quadratic equation.
