Answer:
a) 11mph
b) 6mph
c) 25 miles
Step-by-step explanation:
She can run 12 miles in 2 hours.
She can bike 33 miles in 3 hours.
a) What is Jennifer's biking speed?
Divide:
b) What is Jennifer's running speed?
Divide:
c) Jennifer biked for 2 hours and then ran for 30 minutes. What distance did she cover?
She bikes 11 miles per hour.
2 hours would be = 11mi * 2 = 22miles
She runs 6 miles per hour.
30 minutes or 1/2 hour would be = 6mi * 1/2 = 3 miles
Add these distances.
22+3=25 miles
Answer:
3.7
Step-by-step explanation:
Answer:
0.6625 in²
Step-by-step explanation:
The surface area of this figure will be the area of the base added to area of the triangles
Area of the 4 triangles
Area of a triangle is given by ;
where b is the base length and h is the height of the triangle
<u>Area of 1 triangle</u>
Given base length as 0.25 inches and height is 1.2 inches.
Area of all 4 triangles
- multiply the area of one triangle by 4
- 0.15*4=0.6 in²
<u>Area of the base</u>
The base is a square of length 0.25 inches
Area of a square=length×length
<u>Total surface area</u>
Total surface area= Area of the triangles + Area of the base
