Question

In a pre-election debate, 3 candidates were given equal time to speak. They each spoke for exactly 7/12 of an hour. How long did the 3 candidates speak?

a) 7/12 hours
b) 1/4 hours
c) 21/36 hours
d) 7/6 hours

Answer 1

The three candidates spoke for 7/4 hours, which is equivalent to 1 3/4 hours.

Step-by-step explanation:

The three candidates each spoke for 7/12 of an hour. To find how long they spoke altogether, we need to find the sum of their speaking times. We can simply multiply the amount of time each candidate spoke, which is 7/12 hour, by the number of candidates, which is 3.

Therefore, 7/12 * 3 = 21/12 = 7/4.

So, the three candidates spoke for 7/4 hours, which is equivalent to 1 3/4 hours.
