Question : 16

Total: 50

A temperature of 60º C is equivalent to

25ºF
140ºF
50ºF
108ºF

Solution:

Concept:

Temperature can be converted from Celsius to Fahrenheit using the linear relation between the two scales.

Explanation:

Use the formula

^\circ F = \left( ^\circ C \times \frac{9}{5} \right) + 32

.

Here,

^\circ C = 60

.

Substitute into the formula:

^\circ F = (60 \times \frac{9}{5}) + 32

.

First,

60 \times \frac{9}{5} = 108

.

Then add

32

:

108 + 32 = 140

.

Thus,

60^\circ C = 140^\circ F

.

Answer:

B.

140^\circ F
