Answer 4

What... Um

Answer 5

oops
hold on

Answer 6

@Qwertty123 take the wheel

Answer 7

450 / 90 = 5 because 1.5 hours is 90 minutes

Answer 8

and 280 / 70 = 4
because 70 = 1 hour + 10 mins

Divided! Okay... hold on

Answer 15

okay so this is what I think.
McKenzie: 1 hr + 10 = 70 mins. 70 mins + 120 mins = 840..
Hillary: 90 mins + 120 mins = 210 minutes.
Nicole: 45 mins + 120 mins = 165 mins

270 ÷ 45 = 6

450 ÷ 110 = 4
