Who was the first US president to have lived in the White House?
John Adams and his wife. Even though George Washington was the first US president, John Adams and his wife was the first family to have lived in the White house. It began being built in 1792 and wasn’t inhabited until 1800.
Tommy walked for 2 hours then ran for 1 hour. If she runs three times as fast as she walks and the total trip was 20 kilometers, then how fast does she run?
Let x be the walking speed. 3x will be the running speed. 2*(x) will be the distance walked and 1*(3x) will be the distance run. Total distance is 20 km. So, 2x + 3x = 20 x = 4 km/hr , 3x = 12 km/hr and it is the speed of Tommy when running.
