Answer:
0.8 hours
Explanation:
From the question;
- Speed of Min-jun is 27 miles per hour
- Distance covered is 21 miles
We need to determine the time he takes to cover the distance given;
We need to know that;
Speed = Distance ÷ time
Rearranging the formula;
time = Distance ÷ speed
Thus;
Time = 21 miles ÷ 27 miles per hour
= 7/9 hours
= 0.8 hours
Thus, he took 0.8 hours to cover the distance covered
