2.

An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1 hours, it must travel at a speed of:

Answer: Option

Explanation:

Distance = (240 x 5) = 1200 km.

Speed = Distance/Time

Speed = 1200/(5/3) km/hr. [We can write 1 hours as 5/3 hours]

Required speed = | 1200 x | 3 | km/hr | = 720 km/hr. | |

5 |

How to give 3/5 ?

Mohit said:

It is (3*1)+2=5

So it 5/3 hours and now speed = distance/time that's why 3/5.

So it 5/3 hours and now speed = distance/time that's why 3/5.

The distance wants cover with 1+(2/3)hour is 1200km.

1 + (2/3) = (3+2)/3 = 5/3.

speed=Distance/time

speed=1200km/(5/3)

speed=1200km*(3/5)

speed=720km/hr

1 + (2/3) = (3+2)/3 = 5/3.

speed=Distance/time

speed=1200km/(5/3)

speed=1200km*(3/5)

speed=720km/hr

D= S*T that's why 240 * 5.

Hello! Shwetha, You want to take it as comparison of two plan.

First Plan : 240km * 5hr = 1200km/hr

Second Plan: ? *1+(2/3)= 1200km/hr

First Plan : 240km * 5hr = 1200km/hr

Second Plan: ? *1+(2/3)= 1200km/hr

Distance=240*5=1200

1+2/3=5/3

REQUIRED SPEED=(1200/5/3)

=(1200*3/5)

=720KM/HR

1+2/3=5/3

REQUIRED SPEED=(1200/5/3)

=(1200*3/5)

=720KM/HR

d1=d2

240*5=x*(5/3)

3600=x*5

x=720(km/hr) If both are available in kmphr other we convert them as same.

It is very useful to students. I like this site.

I have doubt in 5/3.

5*240=1200km

1*(sp)=1200km

.'.Speed=1200km/hr this is correct or not ?

5*240=1200km

1*(sp)=1200km

.'.Speed=1200km/hr this is correct or not ?
