Question

The Bionic Woman gives Batman a 12 second

Answer 1

Answer:

Bionic Woman wins by 4 seconds.

Step-by-step explanation:

Given:

Speed of Batman = 3 km/min

Speed of Bionic woman = 5 km/min

Total distance = 2 km

Start given to Batman = 12 seconds

To find:

Winner of the race and by how many seconds?

Solution:

Start given to Batman = 12 second start

Let us find the Distance traveled by Batman in 12 second.

12 seconds = $\frac{1}{5}$ minutes

$Distance = Speed \times Time$

$Distance = 3 \times \frac{1}{5} = 0.6\ km$

Hence, distance left for batman to be traveled = 2 - 0.6 = 1.4 km

Time taken by Batman = $\frac{1.4}{3} \times 60$ seconds = 28 seconds

Distance for Bionic woman to be traveled = 2 km with 5 km/min

Time taken by Bionic Woman = $\frac{2}{5}$ minutes = 24 seconds

Bionic woman is taking lesser time, So the winner of the race will be Bionic woman.

She will win by 28-24 = 4 seconds

So, answer is:

Bionic Woman wins by 4 seconds.
