It takes Emmalyn and her research team, the Polar Bears, 30 minutes to fully navigate around a volcanic island. On Saturday, they decided to start off by rounding the island once. They then re-grouped and planned out the rest of their weekend research schedule. They completed 10 more round that day and then went home. When they came on Sunday, they were able to complete 15 rounds. Calculate the total time, in minutes, the Polar Bears spent circling the island over that weekend.
How many minutes did the Polar Bears spend on the first day? ** On the first day, they started off doing one round of 30 minutes.
How many minutes did the Polar Bears spend on day one? ** The team did ten more rounds on day one which took 10*30 = <<10*30=300>>300 minutes.
How many minutes did the Polar Bears spend on the first day? ** The total time they took circumnavigating the land on the first day is 300+30 = <<300+30=330>>330 minutes.
How many minutes did the Polar Bears spend on the second day? ** On the second day, they did 15 rounds, which took 30 minutes each, giving 15*30 = <<15*30=450>>450 minutes.
How many minutes did the Polar Bears spend circling the island over that weekend? ** The total number of rounds took 330+450 = <<330+450=780>>780 minutes.
