Construction crews A, B,C and D build a 1200 meter long road. Team A builds 1/2 of the total length built by the other 3 teams. Team B builds 1/3 of the total length built by the other 3 teams. C builds a section that is 1/4 of the length built by the other teams. How many meters did Team D build

260 meters.

Step-by-step explanation:

It is given that construction crews A,B,C and D build a 1200 meter long road.

    ...(1)

Team A builds 1/2 of the total length built by the other 3 teams. So,

It means total distance divided in 1:2.

Similarly,

Team B builds 1/3 of the total length built by the other 3 teams.

It means total distance divided in 1:3.

C builds a section that is 1/4 of the length built by the other teams.

It means total distance divided in 1:4.

Now, put A=400, B=300 and C=240 in (1).

Therefore, 260 meters build by D.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

10 * 563.67 = 5636.7
