Well, first we can rule out B and D. When you multiply a positive number by a negative number, you will get a negative number. Since the product of this equation is a positive, we can rule these 2 out. Now we are left with A and C. There are 2 ways you can solve this. You can divide 144 by 16 or 36, or multiply 4 by 16 or 36. I perfer to multiply 4 by A or C. 4 x 16 = 64. So we can rule that one out. SO your answer is C.
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.
