Question

If a man can cover 12 metres in one second,
how many kilometres can he cover in 3
hours 45 minutes?​

Answer 1

Answer:

162 km

Step-by-step explanation:

12 meters in one second

3 hours and 45 minutes = 3.75 hours

∴speed = 12 m/s = 12 m/s × $\frac{18}{5}$ = 43.2 km/h

Now,   speed = $\frac{distance}{time}$

∴            43.2 = $\frac{distance}{3.75}$

∴     distance = 43.2 × 3.75 = 162 km
