Final answer:
Jack will receive £3.65 if he cycles 2.19 km in total for the sponsored cycle.
Step-by-step explanation:
To calculate the amount of money Jack will receive, we need to calculate the number of 0.6 km intervals he cycled. 2.19 km divided by 0.6 km gives us 3.65 intervals. Since he is being sponsored at a rate of £1 per 0.6 km, we can multiply 3.65 by £1 to find that he will receive £3.65 in total.
