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
Answer:
9.37
Step-by-step explanation:
Given your description, we can set up the equation as:
sin(42) = x/14
*Multiply both sides by 14*
x = 14 * sin(42) = 9.37
Answer:
2 5/14
Step-by-step explanation:
Quotient of ¾ and ½:
¾ ÷ ½ = ¾ × 2 = 3/2
1 ⅘ = 9/5
2 1/7 = 15/7
Their product: 9/5 × 15/7 = 27/7
Difference:
27/7 - 3/2
Lcm: 14
[2(27) - 7(3)]/14
(54-21)/14
33/14
2 5/14
