Question

At closing time, 55 adults and 89 students are waiting inline to ride an amusement park roller coaster. The capacityof the coaster is 38 riders. How many trips (t ) must thecoaster make to give all of the people in line a ride?How many people will be on the last trip of the day?

Answer 1

Data

Adults = 55

Students = 89

The total people in the line is 55 + 89 = 144

If every ride takes 38 people, the numbers of trips is expressed as

$t=\frac{144}{38}=3.789\ldots$

Due to the fact that the number is bigger than 3, we assure that the number of trips to ride all the people is t = 4

To know how many people would be on the last trip we must look at the residue of the division.

The residue is 30, which means that in the last trip it will carry only 30 people
