Question

Steve biked 8.4 miles, which was 1.8 miles fewer than Rhonda biked. He wants to write and solve an equation to find r, the number of miles that Rhonda biked. Which are part of the solution? Check all that apply.
To solve, find the total distance that Steve and Rhonda biked; this is an addition problem.
To solve, find the difference that Steve and Rhonda biked; this is a subtraction problem.
To solve, find out how many times more miles that Rhonda rode for; this is a multiplication problem.
Rhonda rode for 10.2 miles.
The correct equation for this problem is r-1.8=8.4. Solve the problem by adding 1.8 to both sides.

Answer 1

Answer:

Option B and D is correct.

Step-by-step explanation:

we are given with the following:

Distance Steve biked = 8.4 miles

Distance Rhonda biked = r

According to the Question,

Steve bikes 1.8 miles less than Rhonda biked.

So,   r - 8.4 = 1.8

or     r - 1.8 = 8.4

add 1.8 on both side

r - 1.8 + 1.8 = 8.4 + 1.8

r = 10.2 miles

Therefore, Option B and D is correct .i.e., To solve, find the difference that Steve and Rhonda biked; this is a subtraction problem.  and Rhonda rode for 10.2 miles.  The correct equation for this problem is r-1.8=8.4. Solve the problem by adding 1.8 to both sides.
