It takes Dare 25 minutes to walk from his house to his school everyday. Lessons start 8.10a.m. and end at 1.40p.m. The school allows 35 minutes for break. If Dare goes straight home after school, at what time should he arrive?

Lessons start at 8.10a.m. and end at 1.40p.m., so the total duration of lessons is 5.30 hours.

The school allows 35 minutes for break, so the total duration of lessons and break is 5.30 hours + 0.35 hours = 5.65 hours.

Dare takes 25 minutes to walk from his house to his school, so the total duration of walking is 25 minutes.

Therefore, the total duration from when Dare leaves his house to when lessons end is 5.65 hours + 25 minutes = 6 hours and 10 minutes.

If Dare goes straight home after school, he should arrive at 1.40p.m. (when lessons end) + 6 hours and 10 minutes = 7.50p.m.
