Question

The distance between Reeta's house and her office is 14 km. She covers 10 km 65 m by scooter, 3 km 75 m by bus, and the rest on foot. How much distance does she cover by walking?

Answer 1

Converting into metres:
10 km 65 m = (10 + 0.065) m = 10.065 m
3 km 75 m = (3 + 0.075) m = 3.075 m

Distance covered by the scooter =                              10.065 km
Distance covered by the bus =                                   + 3.075 km
Total distance covered by the bus and the scooter =  13.140 km

Total distance between the house and the office =      14.000 km
Total distance covered by the bus and the scooter = −13.140 km
Distance covered on foot =                                             0.860 km

∴ Distance covered by walking = 0.860 km = 860 metres
