Equal temperature

The temperatures of the two cities were measured at the same time. The temperature in city A was 60 degrees And rose at a constant rate of 2 degrees per hour.

The temperature in city B was 40° and rose at a constant rate of 10° per hour
Enter the time in hours when the temperature is the same in both cities

Correct result:

t =  2.5 h

Solution:


60 + 2t = 40+10t

60 + 2•t = 40+10•t

8t = 20

t = 52 = 2.5
