Sure, I'd be happy to help with these questions! Let's go through them one by one.
### 37) How much change from £1 if I spend 85 pence?
Firstly, we need to convert the amount of money we're dealing with in consistent units. In this case, let's work in pence since the spent amount is given in pence.
1 pound (£1) is equal to 100 pence (p).
You have spent 85 pence.
To find out how much change you should get:
[tex]\[
\text{Change} = \text{Total amount in pence} - \text{Amount spent in pence}
\][/tex]
Substitute the given values:
[tex]\[
\text{Change} = 100 \text{ pence} - 85 \text{ pence} = 15 \text{ pence}
\][/tex]
So, the change you would receive is 15 pence.
### 38) How many minutes from the time on the clock until 11:40?
To solve the second part, we need to calculate the difference in minutes between the current time and 11:40.
Let's assume the current time is given as `current_time_hours:current_time_minutes`. We'll break this into different scenarios depending on what the current time might be. However, let's pick 10:30 as an example for calculation purposes. If your current hours and minutes differ, you can follow the same steps, just substitute your values.
Let's calculate with current time as 10:30:
1. Current time in hours and minutes: 10:30
2. Future time in hours and minutes: 11:40
First, convert both times to total minutes from midnight:
Current time: 10:30
- Current total minutes from midnight = [tex]\(10 \times 60 + 30 = 600 \text{ minutes}\)[/tex]
Future time: 11:40
- Future total minutes from midnight = [tex]\(11 \times 60 + 40 = 700 \text{ minutes}\)[/tex]
Now, find the difference:
[tex]\[
\text{Difference in minutes} = \text{Future total minutes} - \text{Current total minutes}
\][/tex]
Substitute the calculated values:
[tex]\[
\text{Difference in minutes} = 700 \text{ minutes} - 600 \text{ minutes} = 100 \text{ minutes}
\][/tex]
So, from 10:30 to 11:40, there are 100 minutes remaining. If you have a different current time, just follow the same procedure with your specific hours and minutes.
I hope this helps! If you have any more questions, feel free to ask.
