Jaylen and ken started jogging from the same place in the opposite directions along a straight path. jaylen's speed was 30 m/min

erica [24]

The average speed of Ken is 70 m/min. Using the relation between the speed and distance, the required speed for Ken is calculated.

<h3>What is the relation between speed and distance?</h3>

The relationship between speed S and distance D with a period T is formed as

S = D/T

Units: m/sec (basic unit)

<h3>Calculation:</h3>

Given that,

Jaylen and Ken started jogging from the same place in opposite directions along a straight path.

This means, that the sum of distances traveled by both of them in opposite directions = 13.6 km (since it is given that at the end of their jogging, they are 13.6 km apart)

Consider,

The distance traveled by Jaylen = x km

Then the distance traveled by Ken = x - 2.4 km (since Jaylen jogged 2.4 km more than Ken)

Step 1: Finding the distance traveled by them:

x + x - 2.4 = 13.6

⇒ 2x = 13.6 + 2.4

⇒ 2x = 16

⇒ x = 8 km

So, the distance travelled by Jaylen = 8 km and by Ken = 8 - 2.4 = 5.6 km

Step 2: Finding the average speed traveled by Ken:

Since it is given that,

Jaylen's speed was 30 m/min faster than Ken's speed.

So,

For 30 m, the time = 1 min

then for 2.4 km i.e., 2400 m, the time = 80 min.

Therefore,

the average speed of Ken S = D/t

⇒ S = 5600 m / 80 min

∴ S = 70 m/min.

So, the average speed of Jaylen will be 70 m/min + 30 m/min = 100 m/min.

Thus, the average speed of Ken is 70 m/min.

susan is driving to mount shasta .on her map she is a distance of 7 inches away .the scale of the map is 1/2 inch=50 miles.how f

DochEvi [55]

Answer:

700 miles

Step-by-step explanation:

Given:

Scale of the map is $\frac{1}{2}\textrm{ in}=50\textrm{ mi}$

∴ $1\textrm{ in}= \frac{50}{\frac{1}{2}}=50\times 2=100\textrm{ mi}$

Distance of Susan from mount Shasha on the map is 7 inch.

Therefore, Number of miles = $7\times 100=700\textrm{ mi}$

Hence, Susan must travel 700 miles to reach her destination.

Chen completed the division problem below.

alekssr [168]

<u>Answer:</u>

B. He multiplied the dividend by 100 instead of 10.

<u>Step-by-step explanation:</u>

Chen had to divide $1.926$ by $0.9$ . To make it easier to divide, he thought of multiplying both the dividend and the divisor by 10.

Chen multiplied the divisor by 10 but mistakenly multiplied the dividend by 100 instead of 10.

So his whole division problem was changed.

Therefore, the correct answer option is B. He multiplied the dividend by 100 instead of 10.
