An object travels 8 miles in 20 minutes at a constant speed. What is the object’s speed in miles per hour?
Answers
Answer:
8 miles in 20 minutes
1 hour is equal to 60minutes
8 miles in 20 minutes means
_ miles in 60 minutes?
60÷20 = 3
then we have to multiply 8 three times
8×3=24
then ,the object travels 24miles on per hour
Answer:
24mph.
Step-by-step explanation:
In the question, we're given distance and time. Also, time is in minutes. And we've to find the speed in miles per hour. To solve this question, at first we'll convert time which is in minutes into hour. After that we can easily find the speed using formula.
Distance travelled by an object = 8miles.
Time taken by an object = 20minutes.
Converting minutes into hour
60 minutes = 1 hour
20 minutes = 20/60 = 1/3 hours.
∴ time of object in hour is 1/3 hours.
Now, finding speed.
By formula of speed,
Speed = Distance/Time
⇒ Speed = 8/(1/3) = 8 ÷ 1/3 = 8 × 3
⇒ Speed = 24 miles/hour.
∴ speed of an object is 24mph.
