time taken for car to reach Town A
= 2h 30min = 2.5h
(a)
distance between A and C
= 80 . 2.5 = 200 km
(b)
in 2.5h, the van has travelled
60 x 2.5 = 150 km
distance between B and C
= 150 + 15 = 165 km
time taken for van to reach Town B
= 165/60 = 2.75 h = 2h 45 min
time for van to reach B
= 1130 + 0245
= 1330 + 0045
= 1400 + 0015
= 1415h
OR
(b)
time taken for van to travel another 15 km to reach B = 15/60 = 0.25 h
= 15 min
time taken for van to reach Town B
= 2.5 + 0.25 = 2.75 h = 2h 45 min
time for van to reach B
= 1130 + 0245
= 1330 + 0045
= 1400 + 0015
= 1415h
