Question

a car covers a distance of 16 km in 15 mins .find its speed in km/h​ ?

Answer 1

$hello$

64km/h is the answer to the above question.

Distance = 16km

Time taken = 15 minutes or 1/4 minutes

Speed = Distance/Time

=16÷1/4

=16×4/1

=64km/h

I hope my answer helps you.....✌

Answer 2

Answer:

$\\ \huge\bf \underline\color{black} {\underline{concept - }}$

• As it asked in the question to report the answer in km/hr, we will convert time which is given in minutes to hours using the relation that 1 hour is equal to 60 minutes. Once you have converted the time in hours, use the formula speed= distance/time taken .......this is the answer to the above question. to get the

$\huge \bf\green{solution - }$

• Total distance covered = 16 km

$\\ \bf\red{\: \: \: \: \: \: \: \: \: total \: time \: required = 15 \: min = \frac{1}{4} \: hr} \\ \\ \: \: \: \: \bf \color{lime}{we \: know} \\ \\ \huge \tt\color{aqua}{speed = \frac{distance}{time} } \\ \\ \large \bf \blue{speed = \frac{16}{ \frac{1}{4} } } \\ \bf = \: 64 \: \: \frac{km}{h}$

• Hence speed of train is 64 km/h
