Question

a van can ferry a maximum of 12 people. by setting up an inequality, find the minimum number of vans that we needed to ferry 80 people

Answer 1

Answer:

Given a bus can ferry a maximum of 12 people .by setting up an inquality find minimum number of bus that are needed to ferry 80 people

Given a bus can carry a maximum of 12 people. We need to find minimum number of buses to carry 80 people.

Now 12 people can go in 1 bus.

Therefore 1 person can go in 1/12 bus

Now 1 person can go in 1/12 bus

Therefore 80 people can travel in 1/12 x 80

                                                    = 6.6  

                                                     = 7

Therefore minimum buses needed will be 7

Now we can write inequality as 12 x x > = 80

                     Or x ≥ 80 / 12

        or x > = 6.6

hope it helps

plz mark my answer as the brainliest
