Question

Jaden's mother said he could go ice skating on the pond if the temperature warmed up to at least 15 °F. When he looked at thethermometer, the temperature was -13 °F.How many degrees does the temperature have to rise before Jaden can go ice skating?

Answer 1

28 ºF

Step-by-step explanation

We have to find the difference between the current temperature of -13ºF and the temperature Jaden is waiting for 15ºF:

See in this number line that to get from -13 to 15 we have to go though 0 first. So between -13 and 0 there are 13 degrees. Then from 0 to 15, there are 15 degrees. Therefore, from -13º to 15º there are:

`13+15=28ºF`
