Answer: brianna rode for 54 minutes and maddie rode for 108 minutes.
Explanation:
let the time for which brianna rode be = x
(since maddie rode twice as brianna then,)
let the time for which maddie rode be = 2x
(together they rode for 162 minutes. so,)
x + 2x = 162
3x = 162
x = 162/3
=>x = 54
=>2x = 54*2 = 108
