At 8:00 a.m. the bus started at 18mph, that means it will cover 27 miles in 1hr 30 mins that is by 9:30 a.m. Then after staying for 30 mins it started to return at 10 a.m. This time its speed is increased by 50%, i.e. 27mph (18+9), thus it will cover the return journey of 27 miles in 1 hour, 11:00 a.m.
Thus, the answer is (c). 11:00 a.m.
