There are an infinite number of possibilities, but one of them could be 45/100 or 9/20
B^-2/ab^-3 = b^-2/b^-3 x 1/a = b^[-2-(-3)] x 1/a = b x 1/a = b/a
Answer:
42 minutes
Step-by-step explanation:
Here we want to calculate the number of minutes ran in total.
Kindly note that;
Time = distance/speed
Her starting speed is 10 miles/hour
but she ran for 12 minutes.
Kindly note that 12 minutes = 12/60 = 1/5 = 0.2 hour
So total distance in the first 12 minutes is speed * time = 10 * 0.2 = 2 miles
Now the rest of distance to run would be ;
5 -2 = 3 miles
She ran 3 miles at a speed of 6 miles per hour.
Time spent here is 3/6 = 0.5 hours which is same as 30 minutes
Total time spent = 30 + 12 = 42 minutes
Answer:
Step-by-step explanation:
velocity of turtle = 5 feet / min
velocity of snail = - 11 feet / min
By using the formula of relative velcoity
the velocity of turtle with respect to snail is
V' = velocity of turtle - velocity of snail
V' = 5 - (- 11)
V' = 16 feet / min
