Question

find the missing term that is distance time and speed

D=20km T=1hr 20min​

Answer 1

s=d/t

15 km/h

is your answer

Answer 2

As per data given in the given,

we have to determine the value of speed.

As we know that,

Speed is basically the total distance covered by any body in unit interval of time.

So, for determining the value of speed we will divide the total distance covered by time interval.

So, the value of speed will be

$=\frac{20\:km}{1\:Hr.\:20\:min.}$

As here, time is given in Hour and minute both,

So, we will convert the minute into Hour,

So, we will get.

$=\frac{20}{60} =\frac{1}{3}\:Hr$

So, total time interval will be $=1\frac{1}{3}\:Hr$

So, value of speed will be

$=\frac{20}{\frac{4}{3}}\\=>\frac{20\times 3}{4}\\=15\:kmph$

So, value of speed will be 15 Kmph.
