(a) The 11: 15 bus left the Downtown on time and arrived at Manhattan 2 minutes early. How many minutes did it take to reach Manhattan?

(b) Merry walked to the bus stop at New York and arrived at 12: 56. The next bus arrived on time. How many minutes did Merry wait for the bus?

Explanation

(a) Here, bus left Downtown at 11: 15 and reached at Manhattan 2 minutes early but its arrival time is 11: 29 at Manhattan so it reached at 11: 27.

  • So, 11:15to11:27=2715=12 minutes it had taken to reach at Manhattan.

(b) Here, Merry reached at New York at 12: 56.

  • But last bus was gone at 12: 40 and next bus would come at 13: 20.
  • So, he did wait from 12: 56 to 13: 20 ( 1:20 ) means

20minutes(after1oclock)+4minutes(before1oclock)=24 Minutes.
