ICE Princess25 [194]
G:$2.99
R:$16.99

For every 1R we have 3G.
1R+3G=$16.99+3($2.99)
So 1R+3G=$25.96

If we take $129.80÷$25.96, we get 5.
So let's try 5.

5R+15G=5($16.99)+15($2.99)
So 5R+15G=$129.80

Colleen rode her bicycle 9.5 miles in 0.8 hour. What was her average speed in miles per hour? a 11.875 miles per hour b 10.3 mil
slava [35]

Answer:

Collen's average speed was 11.875 miles/h

Step-by-step explanation:

The average speed is given by the total distance travelled divided by the time at which the route was completed. So in this case the total distance is 9.5 miles and the time to complete it was 0.8 hour. We then have:

average speed = total distance/ time

average speed = 9.5/0.8 = 11.875 miles/h

Collen's average speed was 11.875 miles/h
