In order to understand which one is greater, you need to make the denominator on both fractions equal.

7/3 (2)= 14/6
5/2 (3)= 15/6

Since 15/6 is greater than 14/6:

5/2 is the greater fraction.
Hope this helps!!!

You need to get the denominator at the same number first. The Lowest common denominator is 6. So multiple 7/3 by 2 and 5/2 by 3 to get 14/6 and 15/6. 15/6 is greater. 15/6 is 5/2, so the answer is 5/2. I hope this helps!

A railroad track runs parallel to a highway from City A to City B. An express train and an automobile leave City A at the same t

Nookie1986 [14]

City A is far from City B by 170 miles

Step-by-step explanation:

A railroad track runs parallel to a highway from City A to City B

An express train and an automobile leave City A at the same time
The train travels 85 mph
The automobile travels at 50 mph
The train arrives 1 hour and 24 minutes before the automobile arrives

We need to find how far is City A from City B

Assume that the distance from City A to City B is x mile

∵ Distance = Speed × Time

∴ Time = $\frac{Distance}{Speed}$

∵ The speed of the train = 85 mph

∵ Distance between city A and city B = x miles

∴ The time for the train = $\frac{x}{85}$ hours

∵ The speed of the automobile = 50 mph

∵ Distance between city A and city B = x miles

∴ The time for the automobile = $\frac{x}{50}$ hours

The train takes time less because it travels by high speed

∵ The train arrives 1 hour and 24 minutes early then the automobile

- Change the time to hour only

∵ 1 hour = 60 minutes

∴ 24 minutes = $\frac{24}{60}$ hour

∴ 24 minutes = 0.4 hour

∴ The train arrives 1.4 hours early then the automobile

Now lets subtract the time of the train from the time of the automobile and equate the answer by 1.4

∵ $\frac{x}{50}-\frac{x}{85}=1.4$

- Multiply each numerator by the other denominator and multiply

the two denominators to make the two fraction a single fraction

∴ $\frac{85x-50x}{(50)(85)}=1.4$

∴ $\frac{35x}{4250}=1.4$

- Multiply both sides by 4250 to cancel the denominator

∴ 35x = 5950

- Divide both sides by 35

∴ x = 170

City A is far from City B by 170 miles
