Answer:
55 miles per hour
Step-by-step explanation:
given the originally traveled 40 miles in one hour gives us 40 mph, 180 miles in the last 3 hours gives us an average of 60 mph for the second part, 40+60+60+60 (for the 3 hours going that fast) is equal to 220, divide that by 4 to give us our average of 55 mph

Step-by-step explanation:
Step-by-step explanation:
3 meters = 300 cm
anyway, the ratio tells us that the whole ribbon can be seen as the combination of 3 + 2 = 5 equally long parts.
one such part is then
3 m / 5 = 0.6 m or 60 cm
the shorter piece is 2 of these parts long :
2 × 0.6 = 1.2 m or 120 cm
3: multiply the change per minute by how many minutes: 3.1x15=46.5. 5: Is your opinion, I can't tell you how to feel. But a negative times a negative is a positive, so if there is an even number of negatives no matter how many positives there are it will be positive, if there is an odd number of negatives it will be negative. :) Hope this helps!
