A bus is going to Goa from Pune. With 4 stops of 15 minute each, the average speed of the bus comes out to be 45 m/hr. But if the driver takes the bus without any stops, the average peed comes out to be 50 km/hr.
Answer & explanation
Correct answer: option 2
It is given in the question that ,
There are 4 stops of 15 minutes each.
Total time spent in stops = 4 × 15 = 60 minutes
60 minutes = 1 hour
Let us consider that Time taken without stops = t hours
Formula used is :- Distance = Speed × Time
Distance is same. So,
S1 × T1 = S2 × T2
50 × t = 45 × ( t + 1 )
50t = 45t + 45
5t = 45
t = 9 hours
Distance from Goa to Pune = 50 × 9 = 450 km
