Question

From the town, cars start at regular intervals of 30s and run towards another town with constant speed of
60 km/h. At some point oftime, all the cars simultaneously have to reduce speed to 40km/h due to bad
weather condition. What will be the time interval between arrivals of the cars at the second town during the
bad weather? ( in seconds)
please help! ​

Answer 1

time taken to cover distance 500 meter at speed 40 kmph is 45 seconds.

So answer is 45 seconds.
