Traveling 900 km by rail costs Rs 280 What would be the fare for a journey of 360 km when a person travels by the same class

postnew [5]

Answer:

For 360 km of distance , The cost of fare = Rs 112

Step-by-step explanation:

Given as :

The distance cover by rail = 900 km

The cost of 900 km = Rs 280

Let The cost of journey for 360 km = Rs x

So , ∵ For 900 km of distance , The cost of fare = Rs 280

∴ For 360 km of distance , The cost of fare = $\frac{280}{900}$ × 360

Or, For 360 km of distance , The cost of fare = 0.311 × 360

∴ For 360 km of distance , The cost of fare = Rs 112 Answer

A plane takes off from a runway and begins its climb. The plane takes off at a constant acceleration of 20 LaTeX: m /s^{2} . Onc

lana66690 [7]

Answer:

The plane have traveled 1512.9 m from the time took off

Step-by-step explanation:

Acceleration $a = 20m/s^2$

Initial speed = u = 0

Final speed = v = 246 m/s

Time = t = 93

We are supposed to find how far would the plane have traveled from the time took off

We will use equation of motion

$v^2=u^2+2as\\(246)^2=2\times 20 \times s\\\frac{(246)^2}{2 \times 20}=s\\1512.9 m=s$

Hence The plane have traveled 1512.9 m from the time took off

umka2103 [35]

Answer:

25%

Step-by-step explanation:

So you subtract the number of peak minutes Katie used last month from the number of peak minutes Katie used this month. Divide the difference by the number of peak minutes Katie used last month. Then multiply by 100 to find the percent increase. Katie used 25% more peak minutes this month than last month.
