Answer:
1.8 hours.
Step-by-step explanation:
It is important to note that:
Speed = Distance ÷ Time
We have two trains.
Step 1
We have to find the distance that each train travelled.
Since Speed = Distance ÷ Time
Distance = Speed × Time
First train
It travels at 105 miles per hour
Distance travelled by first train =
105 × x hours
= 105x miles
Second Train
It travels at 85 miles per hour
Distance travelled by the second train = 85 miles × x hours
= 85x miles
We are told that: the two trains leave stations 342 miles apart at the same time and travel toward each other
Hence, the time it would take each train to meet each other is calculated as:
105x + 85x = 342 miles
190x = 342 miles
x = 342/190
x = 1.8 hours.
Answer:
el valor creo que es 2 nooo
16/5. Just divide 48/15 by 3.
Answer:
9cm
Explanation:
A rectangle has two sets of two equal sides. Using this, you can double 35 to get 70 and that is the sum of 2 sides.
Since the entire perimeter is 88, that leaves the rest of the total to be 18.
If you divide 18 by 2 (since there are 2 sides), you get 9. That is the width! Hope this helps.
-72=-9s-45 also equals -9s-45=-72
-9s - 45 + 45 = - 72 + 45
-9s = - 27
-9s/-9 = -27/-9
s = 3
Hope this helped!
