  2. 1224 over 3
  3. 1228 over 9
  4. 1224 over 5

hintHint:

This question is from unitary method and will be solved using unitary method.

The correct answer is: 1224 over 5


    STEP SBY STEP SOLUTION
    Distance covered by aeroplane oin 1 hour = 1020 miles
    Distance covered by aeroplane in fraction numerator 25 over denominator 6 space end fraction space h o u r s space equals space ?
    space 1 space h o u r space equals space 1020 space m i l e s space
space fraction numerator 25 over denominator 6 space end fraction space h o u r s space equals space 1020 space divided by 25 over 6
    space 1020 over 1 space divided by space 25 over 6
space equals space 1020 over 1 space cross times space 6 over 25
space equals space 6120 over 25
space equals space 1224 over 5
    AEROPLANE WILL COVER 1224 over 5 space M I L E S space I N space 25 over 6 space H O U R S space
