The temperature of the compound rose by 2 degrees in one hour
From the question, we are to determine how much the temperature of the compound rise in one hour
From the given information,
The temperature of a compound rose is 1 1/2 degrees every 3/4 of an hour
If the temperature of the compound rises by 1 1/2 degrees every 3/4 of an hour
Then,
The temperature of the compound will rise by x every 1 hour
x = (1 × 1 1/2) ÷ (3/4)
x = (3/2) ÷ (3/4)
x = (3/2) × (4/3)
x = 4/2
x = 2
Hence, the temperature of the compound rose by 2 degrees in one hour
