Question

a train covers a distance of 61 km in 45 mints.how long will it take to cover 305 km​

Answer 1

Answer:

3 hr 45 min

Step-by-step explanation:

$distance = speed \times time$

=>

$speed \: = \frac{distance}{time}$

Speed of train = 61 km / 45 min

Assume the speed is constant to cover 305 km

Let the time taken to cover 305 km be "t" min

=> 61 km / 45 min = 305 km / t min

=> t = 305 * (45 / 61 ) min

=> t = 5 * 45 min = 225 min = 180 + 45 min = 3 hr 45 min
