a few things for it to come down to 1 question ------------------------------------------ 1:A boy cycles 20km in 140 minutes. How long would it take him to cycle 8km, at the same speed? ==== here it is 140mins over 20km, so 140/20 minutes on top --------- 2: It takes a garage owner 45 minutes to travel between his two garages 60 miles apart. Travelling at the same speed, how long would it take him to travel to his home 25 miles away? ======= here its minutes over miles, so 45/60 -------------- 3: A jet travels 320 km in 20 minutes. How far will it fly in 30 minutes? ===== here it's 320km over 20mins, so 320/20 b ------- The question: why is it that minutes are on top of miles despite it being a smaller number, when km is just whatever is larger?
