They both rode at the same speed.

QUESTION: If Jill runs up 10 metres of the hill in 5 minutes, how much does she run in 1 minute?

Jill runs 2 metres up the hill in a minute. 2m/min

PART 2

1) You would have to multiply all the ingredients by 2.5. Because the portion is 4 and to get the portions to 10 is to multiply it by 2.5.

2) I would divide the recipe for 10 buy 10 to get the portion for 1.

DONT FORGET TO STUDY TOMORROW FOR THE TEST! :) GOOD LUCK EVERYONE
