1. Rose went on holiday to the USA. She caught a fever and went to hospital. The nurse took Rose’s temperature every 2 hours. Information about her temperature is given in the table.

Time Temperature (°F)

2 am 101.1

4 am 102.7

6 am 101.8

8 am 101.0

10 am 100.2

a Plot these figures on a suitable graph or chart. (3)

Rose’s normal temperature is 98.6°F.

b Find an estimate of the time at which her temperature will be normal. (2)

In the UK, temperatures are measured in °C. The rule for changing a temperature in °F to the same temperature in °C is

Subtract 32 from the number of °Fthen

Divide by 1.8

c Change Rose’s normal temperature in °F to her normal temperature in °C. (2)

2. Claude set off from home one day to cycle to the market. He started at 10 am and cycled for 1½ hours at a steady speed of 20 kilometres per hour. He then had a rest for 30 minutes before cycling on for another hour at a steady speed of 18 kilometres per hour to reach the market.
