Question on: JAMB Mathematics - 2017
If temperature t is directly proportional to heat h, and when t = 20oC, h = 50 J, find t when h = 60J
A
24oC
B
20oC
C
34oC
D
30oC
Ask EduPadi AI for a detailed answer
Correct Option: A
t ∝ h, t = 20, h
t = ? h = 60
t = kh where k is constant
20 = 50k
k = (\frac{20}{50})
k = (\frac{2}{5})
when h = 60, t = ?
t = (\frac{2}{5}) × 60
t = 24oC
