    Hi everyone. I need help with a temperature problem.

    A thermometer reading 70F is placed in an oven preheated to
    a constant temperature. Through a glass window in the oven
    door, an observer records that the thermometer read 110F after
    ! minute and 145F after 1 minute. How hot is the oven?

    using the following:
    dT/dt = k(T- Tm)

    You might want to proofread your problem before you post it in the correct (calculus) forum ...

    Sorry about that i have been stuck all day with this.

    A thermometer reading 70F is placed in an oven preheated to
    a constant temperature. Through a glass window in the oven
    door, an observer records that the thermometer read 110F after
    .5 minute and 145F after 1 minute. How hot is the oven?

    using the following:
    dT/dt = k(T- Tm)
