Answer 1

ANSWER :

7 : 35 am

EXPLANATION :

Let's sum up the total time John needs for his plan.

It takes 5 hours to drive to Newcastle, 10 mins to fill up fuel and 45 mins for his breakfast.

The total time will be:

$5\text{hrs}+10\text{mins}+45\text{mins}=\text{ 5 hrs and 55 mins}$

So subtracting this total time to 1:30 pm,

Let's substract first the 5 hours,

$1\colon30\text{ less 5 hours is 8 : 30 am}$

Then subtract 30 mins of the 55 mins

$8\colon30\text{ less 30 mins is 8 : 00 am}$

Then the remaining 55 - 30 = 25 mins

Subtract 25 mins from 8 : 00 am

$8\colon00\text{ less 25 mins is 7 : 35 am}$

Therefore, John can leave home at 7 : 35 am
