4 tour groups took a trip to the national museum there are 35 people in each group a maximum of 40 people were allowed on a tour at 1 time what was the least number of tours needed for all the people to take the tour

4 tours.

Step-by-step explanation:

Let x represent number of tours.

We have been given that 4 tour groups took a trip to the national museum.  There are 35 people in each group.

Let us find total number of people in 4 groups.

We are also told that a maximum of 40 people were allowed on a tour at 1 time. So people who will see museum in x tours would be .

The number of people who will visit museum in x tours should be greater than or equal to 140.

Since we cannot take 0.5 of a tour, therefore, the least number of tours that needed for all the people to take the tour would be 4.
