A car travels 195 km in 3 hours.
(i) How long will it take to travel 520 km?
(ii) How far will it travel in 7 hours with the same speed?

Time taken by it to travel 520 km = 520 × 3 = 1560 = 8 hours
195 195

(ii) Distance covered by the car in 3 hours = 195 km
Distance covered by it in 1 hour = 195 = 65 km
