Due to traffic congestion the bus took 20% more timeto travel and took 180 minutes to travel between twocitiies. What could have the time of travel, if therewas no traffic congestion?

Respuesta :

Solution:

First of all, we must find the 20% of 180 minutes:

180 x 0.20 = 36 minutes.

That means that the bus takes an extra 36 minutes in traffic. So that, if there

was no traffic congestion the total time is:

180-36 = 144 minutes.

So that, we can conclude that the correct answer is:

144 minutes.
