What is the distance traveled by the turtle during the seventh minute if it walked 0.3 m in the first minute then it tripled its speed each minute?
by

1 Answer

Answer :

Initial (average) speed = distance/time = 0.3 m / 1 min = 0.3m/minIf it triples its speed every minute:for the second minute it walks at 3 × 0.3m/minfor the third minute it walks at 3² × 0.3 m/minfor the nth minute it walks at 3ⁿ⁻¹ × 0.3 m/min→ for the 7th minute it "walks" at 3⁷⁻¹ × 0.3 m/min = 3⁶ × 0.3m/min (approx 13 km/h or 8 mph; we generally walk at 2 to 3mph)→ distance = speed × time→ distance in 7th minute = 3⁶ × 0.3 m/min × 1 min = 3⁶ × 0.3 m =218.7 m

If the cost price of shoes doubles, then the loss gets tripled of what it was initially. The initial loss % was ?

Description : If the cost price of shoes doubles, then the loss gets tripled of what it was initially. The initial loss % was ?

Last Answer : Let the cost price be y and selling price be z.  Loss = y-z  When the cost price doubles, the loss gets tripled.  So it becomes like this, 2y – z = 3(y-z)  y=2z  Loss % = (2z-z/2z*100) = 50 %

Four members of a band are walking to a night concert. They decide to take a shortcut, but must cross a bridge. Luckily they have one flashlight. Because of the varying size of their instruments, it takes each member a different amount of time to cross the bridge - it takes the first person one minute, the second person two minutes, the third person five minutes and the fourth person ten minutes.
