Question

You know your school bus stops at 2-minute intervals. The first stop of the route begin at 6:20 a.m. every day. If your stop is the 18th stop , when will the bus arrive for you ?

Answer 1

6:54 am

= when the bus arrives for you

it starts at 6:20 am

stops every 2 minutes

you're it's 18th stop

that means 17 previous stops

2x17 =34

20+34 = 54 minutes after 6 am= 6:54 am

Answer 2

The first stop occurs at 6:20 a.m.

There will be 17 more stops before we reach the 18-th stop. 17 × 2 minutes = 34 minutes.

6:20 a.m. + 34 minutes is 6:54 a.m.
