8th grade math question

Answer 1

360 mph; you just have to multiply the bottom row by 6 to get the top row, so 30•6=180 and 60•6=360

Answer 2

$Distance=60+180+540+660=1,440\ mi\\Time=10+30+90+110=240\ min\\\\1h=60min\to1min=\dfrac{1}{60}h\\\\240\ min=240\cdot\dfrac{1}{60}h=4h\\\\v=\dfrac{d}{t}\to v=\dfrac{1,440}{4}\ mph=360\ mph$

Answer: 360 mph
