    63.5minutes

    Step-by-step explanation:

    Let the time it takes the small pipe to fill the tank be x

    Let the time it takes the larger pipe to fill the tank be y

    If the two pipes can fill a tank in 98 minutes if both are turned on then:

    x+y = 98 ... 1

    If only one is used and it takes 29 minutes longer for the smaller pipe to fill the tank than the larger pipe

    x = 29+y ... 2

    Substituting equation 2 into 1 to get y we have:

    29+y+y = 98

    29+2y = 98

    2y = 98-29

    2y = 69

    y = 69/2

    y = 34.5minutes

    x = 29+34.5

    x = 63.5

    This means it will take the smaller pipe 63.5minutes to fill the tank
