Hint: In order to solve this problem apply the formula of speed i.e. speed is equal to distance upon time. We have speed and distance. Here we have to find the time. so apply this speed formula. Doing this will solve your problem.

Complete step-by-step answer:

Let the distance given is d = 250 km

Speed to cover this distance is s = 20km/hr

As we know, ${\text{speed = }}\dfrac{{{\text{distance}}}}{{{\text{time}}}}$

Therefore, ${\text{time = }}\dfrac{{{\text{distance}}}}{{{\text{speed}}}}{\text{ = }}\dfrac{{\text{d}}}{{\text{s}}}$

${\text{time = }}\dfrac{{\text{d}}}{{\text{s}}}{\text{ = }}\dfrac{{{\text{250}}}}{{{\text{20}}}}$

Therefore, time = $\dfrac{{{\text{250}}}}{{{\text{20}}}}$=12.5hr

Hence the time taken to cover 250 km with speed 20km/hr is 12.5hr.

Note: Whenever you face such types of problems you have to apply the formula of speed equals distance upon time. After putting the values in the formula you have to solve and get the term which has been asked. Proceeding in this way will reach you till the right answer.
