I made up this math problem, how to solve? [I Love Math]

You can see next to my name I'm in my 30s so this isn't homework I'm just bored.

I am not great at math but trying to improve my skills, this happened earlier, how would I solve?

I wanted to cook microwave Salisbury Steak, and I live in a studio apartment. My air conditioner has been set to 70 degrees for the past few hours.

I put the steak in the microwave and microwaved for 7 minutes and flipped it half way per the instructions. The box says it needs to be 165 degrees. Then I took it out to cool, my microwave is 1400 watts and 7 minutes was the max time for a 1200 watt oven.

Then I got a work call and got sidetracked for 25 minutes. If I check the temperature with a thermometer, what reading should I get to know my food is properly cooked?

Unusual to see microwave-cookery instructions use temperatures, in the way conventional oven cooking instructions have to do. Or is this for a microwave oven fitted with a grill?

Normally the instructions use power (Watts) and time, and a meal manufactured to be cooked in a microwave oven will have been designed and tested to be cooked at the specified settings.

You need use some judgement if your oven is lower-powered than stated on the packet, but normally the food manufacturer gives the times for more than one power, so you can work out the extra time for lower power.

I have to do that regularly because my µ-wave oven is rated at only 700W. E.g. if the label states 5 minutes at 1000W and 5m 30s for 850W, I cook it for 6 minutes at 700W.

The room temperature is not relevant to the cooking. So ignore your heating or air-conditioning settings.

So don't over-complicate things. Just follow the instructions on the packet!

To test meat for full cooking, push a skewer or fork into it. If fully cooked the emerging juice will be clear.
