You just need to find out when 110t + 90t = 350 or when 200t = 350.
200t = 350 (divide both sides by 200)
t = 1.75k/h which is the same as 1 hour, 45 minutes.
If car a is going 110k/h for 1.75 minutes, it will be 192.5k along its way. If car b is going 90 k/h for 1.75 minutes, it will be 157.5k along the way.
192.5k + 157.5k = 350k … in other words, they’ve met

the cars travel a combined distance of 200km per hour and they need to travel 350 km.. so, it will take them 1 3/4 hours to reach each other
