Answer:
240.8
Step-by-step explanation:
→ Calculate time taken
16:43 - 14:56 = 1 hour and 47 minutes
→ Write the speed formula and make distance the subject
Speed = Distance ÷ Time ⇔ Distance = Speed × Time
→ Convert 1 hour and 47 minutes into decimal format
1.78333333 or
→ Substitute values into formula
135 × = 240.75
NO. The mirror will not fit in a space that is 15 inches by 16 inches
<em><u>Solution:</u></em>
Given that area of mirror is 225 square inches
Converting the above mixed fraction we get,
Let us find the length of mirror
The area of mirror is given as:
area of mirror = length x width
Substituting the given values,
Thus length of mirror is 16.36 inches
<em><u>Will the mirror fit in a space that is 15 inches by 16 inches?</u></em>
NO. The mirror will not fit in a space that is 15 inches by 16 inches
Because length of mirror is 16.36 inches whereas the given space is 15 inches long
16.36 > 15 so the length of mirror will not fit inside the space
Also width of mirror is inches which is less than the given space whose width is 16 inches
13.75 < 16 so the width of mirror will not fit inside the space
