Answer:
Todos los días voy a la escuela en bicicleta, queda a quince minutos de mi casa.
Al llegar a la escuela le doy la tarea a mi maestra.
Soy alta, amigable e inteligente aunque a veces me cuesta hacer la tarea de matemática.
Explanation:
These three sentences in English would be something like this:
Every day I go to school by bike, it's fifteen minutes away from home.
When I get to school I give my teacher my homework.
I'm tall, friendly and smart, although I sometimes find my maths homework hard to do.
The three are in the present tense as they refer to daily habits and to characteristics about someone (in this case, myself)
