Question

If Krish rides south on his bicycle in a straight line for 15 min with an average speed of 12.5 km/h. How far has he ridden?

Answer 1

Answer:

Distance = speed × time

= 12.5 × 1/4 of an hour

= 12.5 × 0.25

= 3.125 km

Answer 2

Answer:

Krish has ridden 3.125 km.

Explanation:

firstly time have to convert in hours

$15min = \frac{15}{60} hr = 0.25hr$

Now ,

we know the formula of distance as

$velocity \: = \frac{distance}{time} \: \: \: \: \: \: \: \: \: \: \: \: \\ distance = velocity \times time$

putting all values ,

we get

$distance = 12.5 \frac{km}{hr} \times 0.25hr$

$distance \: = 3.125 \: km$
