Brianna and maddie rode their bikes on saturday. maddy rode twice as much as brianna. together they rode for 162 minutes. how many minutes did each girl ride?

brianna rode for 54 minutes and maddie rode for 108 minutes.

Step-by-step 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
