Complete question :

In Hawaii a volcano is about to explodel At 6:00 am a device placed inside the volcano

measures the temperature at 69.5 degrees Celsius. Every 3 minutes the temperature

rises 1/5 a degree. If the Volcano explodes at 145.5 degrees Celsius how many hours do

they have to evacuate a nearby city?

Will Mark BRAINLIEST to the correct answer

19 hours

Step-by-step explanation:

Given that:

Temperature of volcano at 6:00 am = 69.5°C

Average rise in temperature per 3 minute = 1/5

Hence, rise in temperature per minute = 0.0666666°C

Temperature at which volcano will explode = 145.5°C

Hence, change in temperature :

(145.5°C - 69.5°C) = 76°C

Hence, temperature will have to rise by 76°C

Rise in temperature / rate of temperature increase

= 76°C / 0.0666666°C

= 1140.0011 minutes

= 1140.0011 / 60

= 19.0000019 hours

= 19 hours
