65+45= 100 The trucks are moving away from each other at 100mph. They will be 327 miles apart in 3 hours 16 minutes and 12 seconds. This is why:
327/100= 3.27 So we have 3 hours and a remainder of 0.27. There are 60 minutes in one hour: 0.27*60= 16.2 So that's 16 minutes and we have .2 left over. A minute has 60 seconds and .20*60= 12 seconds. Put it all together and we get 3 hours 16 minutes and 12 seconds.
