Answer:

  • My little brother will have to wait for 12.5 minutes to drink his hot chocolate.

Step-by-step explanation:

We know that in 5 minutes, the temperature of the hot chocolate decreased by 10 degrees. We also know that the temperature is fixed at 70 degrees. Now, using the info given, let's solve!

  • => 5 minutes = 10 degrees decrease
  • => 1 minute = 2 degrees decrease
  • => 1 minute x 12.5 = 2 x 12.5 degrees decrease
  • => 12.5 minutes = 25 degrees decrease

Conclusion:

Therefore, my little brother will have to wait for 12.5 minutes to drink his hot chocolate.
