① When the two vehicles meet on the way, the distance of vehicle a is 60% of that of vehicle B. after the two vehicles meet, the speed of the two vehicles is the same When car B arrives at a, car a is 64 kilometers away from B, and how many kilometers does car a travel? ② car a and car B start from ab at the same time, and run in opposite directions. When the two cars meet on the way, car a drives 40% of ab. after meeting, the two cars continue to drive at the same speed. When car B arrives at a, car a has driven 90 kilometers, and how many kilometers is the distance between AB and car B

one
Speed ratio = distance ratio = 3 / 5
Distance between the two places = 64 (1-3 / 5) = 160 km
Car a has traveled 160-64 = 96 km
Car a has traveled 96 kilometers
two
90÷【40%/（1-40%）】
=90÷2/3
=135 km
