The schedule of a train that travels regularly between Pune and Delhi is given below. Station Arrive Depart Pune 5:30 a.m. 6:00 a.m. Mumbai 8:15 a.m. 8:30 a.m. Surat 4:30 p.m. 5:10 p.m. Mathura 12:40 a.m. 1:25 a.m. Delhi 4:40 a.m. −− How long will it take Sam to travel from Pune to Delhi on this train? hours minutes

Answers


To determine the travel time, we need to calculate the time difference between the departure from Pune and the arrival in Delhi. According to the schedule:

Pune departure: 6:00 a.m.
Delhi arrival: 4:40 a.m.

To calculate the travel time, we can subtract the departure time from the arrival time. However, since the arrival time is the next day, we need to consider that as well. Let's break it down:

From Pune to Mumbai: 8:30 a.m. - 6:00 a.m. = 2 hours and 30 minutes
From Mumbai to Surat: 5:10 p.m. - 8:30 a.m. = 8 hours and 40 minutes
From Surat to Mathura: 1:25 a.m. - 4:30 p.m. = 11 hours and 55 minutes
From Mathura to Delhi: 4:40 a.m. (next day) - 12:40 a.m. = 4 hours

Now, let's add up the individual travel times:

2 hours 30 minutes + 8 hours 40 minutes + 11 hours 55 minutes + 4 hours = 27 hours 5 minutes

Therefore, it will take Sam approximately 27 hours and 5 minutes to travel from Pune to Delhi on this train. ⏰

The product of (3+2i) and a complex number is (17+7i)

What is the complex number.

Answers

The question is asking us to find the complex number such that: ( 3 + 2 i ) * x = 17 + 7 i. We know that i^ 2 = - 1. x = ( 17 + 7 i ) / ( 3 + 2 i ) . We have to multiply the numerator and the denominator by ( 3 - 2 i ). Then: x = ( 17 + 7 i ) * ( 3 - 2 i ) / ( 9 - 4 i^2 ) = ( 51 - 34 i + 21 i - 14 i^2 ) / ( 9 + 4 ) = ( 51 + 14 - 13 i ) / 13 = ( 65 - 13 i ) / 13 = 65 / 13 - 13 i / 13 = 5 - i. Answer: The complex number is 5 - i.
