Question

Min-jun travels 27 miles per hour. How long does it take him to travel 21 miles. Nearest tenth

Answer 1

Answer:

0.8 hours

Step-by-step 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
