How can you find a unit rate when given a rate?

1 answer:

7 0

It depends on the problem really. One example is that you drive 10 miles in 2 hours. So you divide the distance over time to get 10/2 = 5. This means you drove 5 miles per hour (mph). The unit rate for this example is 5 mph.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 95 miles per

alisha [4.7K]

Answer:

It will take 1.6 hours for the two trains to be 336 miles apart.

Step by step explanation:

Given that:

Speed of eastbound train = 95 miles per hour

Speed of westbound train = 115 miles per hour

Combined speed = 95+115 = 210 miles

Distance = 336 miles

$Speed = \frac{Distance}{Time}\\\\210 = \frac{336}{Time}\\\\Time = \frac{336}{210}\\\\Time = 1.6\ hours$

Hence,

It will take 1.6 hours for the two trains to be 336 miles apart.

Kali left the White House and traveled toward the lake. Ndiba left one hour later traveling 15 mph faster in an effort to catch

CaHeK987 [17]

Answer:

The speed of Kali is 30 mph.

Step-by-step explanation:

Let, the speed of Kali be "x", then speed of Ndiba will be:

Speed of Ndiba = x + 15 mph

If, the time for travel for Ndiba is 2 hrs, when he catches Kali, and he left 1 hour later than Kali, then then time traveled by Kali at that instant will be 2+1 = 3hrs.

At the point of meeting both will have covered same distance.

Distance Covered by Kali = Distance Covered by Ndiba

(Speed of Kali)(Time traveled by Kali) = (Speed of Ndiba)(Time traveled by Ndiba)

(x)(3) = (x +15)(2)

3x = 2x +30

The correct answer is, actually 30 mph, by the solution shown above.
