Answer:
6 mph
Step-by-step explanation:
3 miles -----> takes 30 minutes
recall that 30 minutes = 1/2 an hour = 0.5 hours
hence,
3 miles -----> takes 30 minutes = 0.5 hrs
therefore her rate of change (i.e speed) in mph
= number of miles ran ÷ time taken in hours
= 3miles ÷ 0.5hrs
= 6 mph
Answer:
curious if you got this one?
Which does NOT represent a constant rate of change of 70 miles per hour for a car?
Question 4 options:
The car travels 245 miles in 3.5 hours.
The car travels 140 miles in 2 hours.
d = 70t, where d represents distance in miles and t represents time in hours.
d = 70t, where d represents distance in kilometers and t represents time in hours.
Step-by-step explanation:
Step-by-step explanation: The commutative property of multiplication states that changing the order of the factors does not change the product.
Example:
4 × 10 ≈ 10 × 4
If we multiply both these numbers together, we will get the same answer which is 40. This means that 4 × 10 must be equal to 10 × 4.
Example:
3 × 2 ≈ 2 × 3
Both of the answers will equal 6 which means that they are equal to each other.

Answer:
A = 4 * 2 1/2
A = 4*5/2
Step-by-step explanation:
