# Unit 12 Section 2 : Problems with Arithmetic

In this section we look at problems in practical contexts which can be solved using arithmetic.

## Example Questions

(1) Sarah buys 8 ice creams costing 95p each. How much does she spend?

The answer is 8 × 95p = 760p = £7.60

(2) It takes Paul 22 minutes to wash a car. How many cars can he wash in 1 hour and 50 minutes?

We need to find out how many times 22 minutes goes into 1 hour and 50 minutes.
1 hour and 50 minutes is the same as 110 minutes, so the answer is 110 ÷ 22 = 5 cars
