Answer 2

Answer:

7hr 20 min

Step-by-step explanation:

distance=speed×time

total distance =50km×3hr= 150km

speed of bus is

50 - 40% of 50 = 30km/hr

time taken by bus without stopping

150/30 =5hr

since bus stops for 10 min at each 10km

150km/10km = 15 stops

but last stop we are not considering

because its the destination.

14 stops ×10 min =140 min

so total time spent will be 5hr + 140min ie,

7hr 20min
