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:
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 |

s = d/t.
s1 = d1/t1.
s2 = d2/t2.
s1t1 = s2t2/distance is same.
t2 = s1t1/s2.
t2 = 240*5/(5/3).
t2 = 720.
s1 = d1/t1.
s2 = d2/t2.
s1t1 = s2t2/distance is same.
t2 = s1t1/s2.
t2 = 240*5/(5/3).
t2 = 720.

1*2/3 is a mixed fraction, we are converting it into improper fraction as 5/3.
S=d/t=1200/(5/3)=1200*3/5=720.
S=d/t=1200/(5/3)=1200*3/5=720.

We can calculate like below right?
Per hour 240 KM & for 5 hour, 1200KM.
1200/1.666 = 720.
Is that right?

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

Distance= s * t so 12 * 20 = 240,
Spd = d/t.
t = 15.
Distance = d/t
= 240/15 = You will get the Answer.
Spd = d/t.
t = 15.
Distance = d/t
= 240/15 = You will get the Answer.

And it's not 1+2/3, it is 1*2/3 which means 1 hour and 2/3 minutes.
1*2/3 evaluates to (3*1+2)/3=5/3 hrs.
1*2/3 evaluates to (3*1+2)/3=5/3 hrs.

1(2/3) is a mixed fraction.
= 1*2/3.
= Now we have to multiply denominator to 1 (1*3)
=3 + 2/3 = 5/3.
= 1*2/3.
= Now we have to multiply denominator to 1 (1*3)
=3 + 2/3 = 5/3.

240 Km/hr in 5 hours
5X60=300min
in 1 2/3 hrs to travel the same distance
1 2/3X60=100
=240/100X300=720
5X60=300min
in 1 2/3 hrs to travel the same distance
1 2/3X60=100
=240/100X300=720

There are 3 speeds 12m, 14m and 16m covering equal distance. What is the average speed? please solve it.

Distance = (240*5) = 1200km.
Speed = Distance/Time.
Speed = 1200/(5/3) km/hr.
= 1200*3/5.
= 720 km.
Speed = Distance/Time.
Speed = 1200/(5/3) km/hr.
= 1200*3/5.
= 720 km.
