Answer:
53 1/3 km/h
Step-by-step explanation:
average speed = (total distance)/(total time)
average speed = distance/time
time * average speed = distance
time = distance/(average speed)
250 km at 75 km/h
distance = 250 km
time = (250 km)/(75 km/h) = 3.33333... hours
350 km at 70 km/h
distance = 350 km
time = (350 km)/(70 km/h) = 5 hours
200 km at 30 km/h
distance = 200 km
time = (200 km)/(30 km/h) = 6.6666... hour
total distance = 250 km + 350 km + 200 km = 800 km
total time = 3.33333... hours + 5 hours + 6.66666... hours = 15 hours
average speed = (total distance)/(total time)
average speed = (800 km)/(15 hours)
average speed = 53 1/3 km/h
To complete the equation and tell which property you used.
(3×10)×8=___(10×8)
The property of basic operations that was used here is the:
1. Associative property of
multiplication where you can group or cluster certain values or numbers in an
equation and still yield the same product.
The missing value would be 3. Hence,
2. (3 × 10) × 8 = 3 (10 × 8)
Observe the parenthesis which has only moved from starting with three to
the value of ten.
$15 that the answer. Your welcome
