Distance divided by speed will give you time taken for the journey so qn 10 should not be hard.

Qn 11 requires only simple algebraic manipulation. Cross multiply and you should be able solve both question

For qn 12, as long as you can establish the fraction to be x/(x+3) and that (x+4)/(x+7) = x/(x+3) + 4/15, you can solve the question quite easily. Remember to reject the negative answer as the question only wants a positive fraction
