Answer:
80 mph
Step-by-step explanation:
step 1
Find the distance traveled by Miriam the first two hours
Remember that the distance is equal to the speed multiplied by the time
we have
so
9:00 AM +2 h=11:00 AM
At 11:00 am Miriam has travel 140 miles
step 2
Find out the speed
Remember that the speed is equal to divide the distance by the time
The time is equal to
6:00 PM-11:00 AM=7 h
the distance is equal to
700-140=560 miles
therefore
I think 678 to the nearest hundred is 700.
Answer:
Three equivalent ratios of are , and .
Step-by-step explanation:
We are given a fraction .
We need to find the three equivalent ratios/fractions of .
The common factor of 14 and 2 is 2.
So, dividing top and bottom by 2, we get
14÷2 = 7 and 2÷2 that is .
Multiplying fraction by a common number 3 in top and bottom, we get
7 × 3 = 21
1 × 3 = 6
So, we get another equivalent fraction .
Multiplying fraction by a common number 3 in top and bottom, we get
7 × 4 = 28
1 × 4 = 4
So, we get another equivalent fraction .
Therefore, three equivalent ratios of are , and .
Answer:
igneous
Step-by-step explanation:
Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.
