We need to find how many students have at least one social media account.
We know that there are 120 students in the class.
We also know that there are 65% of students that have at least one social media account.
To find your answer, would multiply 120 by 0.65:
120 · 0.65 = 78
This means that 78 of the students has at least one social media account.
Answer:
78 students
Find the speed of the train:
67.5 mi
---------- = 45 mph
1.5 hr
Then (distance traveled) = (speed)*(time) => d = (45 mph)(t)
(B) 4 hr is the correct answer.
<h3><u>Explanation</u> :</h3>
★ Speed of body is defined as the ratio of distance travelled to the time taken
Given that,
distance = 56 miles
speed = 14 miles per hour
<u>By</u><u> </u><u>subs</u><u>tituting</u><u> </u><u>the</u><u> </u><u>values</u><u>,</u><u> </u><u>we</u><u> </u><u>get</u>
⭆ time = distance/speed
⭆ time = 56/14
⭆ <u>time = 4 hr</u>
