Two cars, A and B, leave from A and B at the same time and go in opposite directions. A few hours later, they met. After meeting. Continue to drive at the original speed. After 5 hours, bus B arrives at location A, and car A exceeds location by 45 kilometers, accounting for 25% of the whole journey between location A and location B. How many kilometers does car A travel per hour?
( 1+25%): 1=5:4
5× 4/5 = 4 (hour)
45 ÷ 25% = 180 (km)
(180+45) ÷ (4+4) = 28.125 (km)
