Question

You know your school bus stops at 2 minute intervals the first stop of the route begins at 6:20 AM everyday if your stop is the 18 stop when will the bus arrive for you?

Answer 1

`"6:56 am"`

Explanation:

Multiply `2` minutes by `18` stops to find the number of minutes it will take for the bus to start the route to get to stop `18`.

`2 xx 18 = 36` minutes

To get the time, add `6:20 + 0:36`, giving you `"6:56 am"`.

Answer 2

`6:56 AM`

Explanation:

Actually this is not a true model. It does not allow for entry or exit time onto or off the bus. For this to work it implies that there is 0 time allowed for getting onto the bus.

2 minute intervals gives a total time of `2xx18 = 36` minutes to arrive at your stop.

Start time is: `color(white)("dddd")"hours"color(white)("d")" minutes"`
`color(white)("ddddddddddddddd")6color(white)("dddddd")20`
Time to the stop`ul(color(white)("dddddddddd")36 larr" Add")`
`color(white)("ddddddddddddddd")6color(white)("dddddd")56`

As the 56 minutes is less than 1 hour we have nothing to carry over into the hours. Thus the time of arrival is: `6:56 AM`
