Let x represent the number of minutes that Eric drove.
Tyler drove twice as long as Eric. This means that the distance that Yyler drove is 2x
Joc drives 25 minutes more than Eric. This means that the distance that Joc drove is x + 25
If they drove for a total of 145 minutes, it means that
x + 2x + x + 25 = 145
4x + 25 = 145
4x = 145 - 25
4x = 120
x = 120/4
x = 30
Eric drove for 30 minutes
Tyler drove for 2 * 30 = 60 minutes
Joc drove for 330 + 25 = 55 minutes
