A bus travels at 100 km/h for the first 1/2 hour. Later it travels at 80 km/h. Find the time taken by the bus to travel 290 km.
A4 hours
B3.5 hours
C3 hours
D2.5 hours
Answer:
B. 3.5 hours
Read Explanation:
Distance travelled in first 1/2 hours
= 100 × 1/2
= 50 km
Remaining distance= 290 - 50 = 240 km
Time taken to travel remaining distance at 80 km/h
= 240/80
= 3 hours
Total time to travel 290 km = (1/2+ 3) hours
= 3.5 hours
