Answer:
(D) Divide the first equation,
, by 2.
Step-by-step explanation:
Given:

We need to find the operation performed on equation so as to get resultant equation as:


From Above we can see that there is no change in equation 2 with respect to resultant equation.
Also Resultant equation is simplified form of equation 1.
Simplifying equation 1 we get;

We can see that 2 is the common multiple on both side.
Hence we will divide equation 1 with 2 we get

which is the resultant equation.
Hence (D) Divide the first equation,
, by 2 is the correct option.

Answer:
Speed of turtle = 11.25 miles/hour
Step-by-step explanation:
1 7/8 miles / 1/6 hour
= 15/8 / 1/6
= 15/8 * 6
= 11.25 miles/hour
10.25 hours on average
8+12+12+9=41
41/4= 10.25
