First we need to find out the time it took for the truck to reach town B.
Now, because the van left 1.5 hours earlier and reached the destination 2.5 hours before, it took 1 hour less the the truck to arrive.
which is the time it took for the van to arrive.
Now we use the speed equation again to work out speed.
= speed of van
Hope this helped :)
