so 51+51=102 and then 10+10+10+10=40, and 102+40=142. So they will need to take 2 buses and 4 vans.
hope I helped

Answer: The answer is 2 buses and 4 vans.


Step-by-step explanation: Let 'b' be the number of buses and 'v' be the number of vans that will be needed.

The trip will use 6 drivers, and we need one driver for each vehicle, so number of drivers is equal to the number of vehicles used.i.e.,


b+v=6.

Now, number of passengers in buses is 51b and number of passengers in vans is 10v. Since there are total 142 people, so


51b+10v=142.

Substituting the value of 'v' from forst equation in the second equation, we have


51b+10(6-b)=142\\\\\Rightarrow 51b+60-10b=142\\\\\Rightarrow 41b=82\\\\\Rightarrow b=2.

Again, from the first equation, we get


v=6-2=4.

Thus, there are 2 buses and 4 vans in the trip.
