Primeiro, convertemos todas as interrupções de tempo para minutos:

- 1 hora e 30 minutos para o almoço:

1 \text{ hora} = 60 \text{ minutos}

1 \text{ hora e 30 minutos} = 60 + 30 = 90 \text{ minutos}

- 45 minutos para o lanche:

45 \text{ minutos}

- 30 minutos com idas ao banheiro:

30 \text{ minutos}

- 30 minutos para hidratação:

30 \text{ minutos}

Agora, somamos todos os minutos usados para as paradas:

90 + 45 + 30 + 30 = 195 \text{ minutos}

Convertendo 10 horas para minutos:

10 \text{ horas} = 10 \times 60 = 600 \text{ minutos}

Calculando o tempo restante estudando:

600 - 195 = 405 \text{ minutos}

Para encontrar o percentual de tempo gasto estudando, usamos a fórmula:

\left( \frac{405}{600} \right) \times 100 \%

Simplificando:

\left( \frac{405}{600} \right) \times 100 \% = 0.675 \times 100 \% = 67.5\%

Por fim, arredondamos para o valor mais próximo:

67.5\%

Portanto, o percentual de tempo em que a Fernanda passa estudando dentro dessas 10 horas é:

67.5\%
