Question

If a person swims 120 in a minute what is his speed in kilometre per hour and minutes per second how much time will it take to swim a distance of 45 M with a bow speed how much distance will he cover in 50 seconds

Answer 1

Explanation:

$120m |min \:$

$\frac{120m}{60s} = \frac{2m}{1s}$

$\frac{2 \times 50}{1 \times 50} = \frac{100m}{50s}$

$\frac{2 \times 45}{1 \times 45} = \frac{90m}{45s}$
