Question

car takes 20 minutes to cover a distance of 15 km calculate it's speed?​

Answer 1

Answer:

45 km /h

Explanation:

speed =distance/time taken

15 /20 = 45

Answer 2

Here it is given that

We have to calculate the speed,

The formula for the speed is-

Speed = $\frac{distance}{time}$

As we have,

Time = $20$ minutes = $\frac{20}{60}$ hrs

Distance = $15$km

By using the formula,

$=>S=[\frac{15}{\frac{20}{60} }]km/hr$

$=>S=[\frac{15}{\frac{1}{3} }]$

$=>S=15\times 3$

$=>S=45$km/hr

Now, by converting km/hr to m/s

We need to divide the value of speed by $3.6$,

$=>S=\frac{45}{3.6}$ m/s

$=>S=12.5$ m/s

Hence, the value of speed is $12.5$m/s
