Question

A car cover a certain distance in 50 minutes if it cover a 45km/hr.How much time will it take to cover the same distance at a speed of 30km/hr?

Answer 1

Hey folk !!

Here's the answer you are looking for

In the 1st case,

Time taken = 50 mins = 5/6 hours

and speed = 45km/hr

So, distance travelled = speed × time

= 45 × 5/6

= 75/2 km

In second case,

distance remains same that is 75/2 km

and speed becomes 30km/hr

$So, \: time \: taken \: = \: \frac{distance \: travelled}{speed} \\ \\ = \frac{75 / 2}{30} \\ \\ = \frac{75}{2 \times 30} hr \\ \\ = \frac{75}{60} \times 60 \: mins \: = 75 \: mins \: (ans.)$
