Answer:
He will ride his bicycle for 72 hours and jog for 96 hours.
Explanation:
David rode his bicycle for 6 hours and he jogged for 8 hours during the past 2 weeks.
We can say that per week, he rode his bicycle for 3hours and jogged for 4 hours.
Assuming that he continues at the same rate, in 24 weeks, he will ride his bike for:
24 * 3 = 72 hours
And he will jog for:
24 * 4 = 96 hours.
He will ride his bicycle for 72 hours and jog for 96 hours.
