To find the distance an object has traveled, you use the formula D=RT; where D=distance, R=rate and T=time. What was the rate a person drove if they traveled 313.5 miles in 4 hours? A. 78.374 miles per hour B. 78.375 miles per hour C. 1,254 miles per hour D. 12,540 miles per hour

78.375 miles per hour = R

Step-by-step explanation:

D= RT

The miles are 313.5 which is D and the time is 4 hours

313.5 = R * 4

Divide each side by 4

313.5/4 = R

78.375 miles per hour = R

21/58.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
