Question

If a car travels 60 km in an hour, how far will it travel in

(1) 2 hours? 

(2) 15 minutes? 

(3) half an hour? 

(4) three and a half hours?

Answer 1

60 kmph

In 60 minutes 60 km

Hence, 1 minute 1 km

(1) 2 hours = 2 x 60 = 120 km

(2) In 15 minutes = 15 km

(3) In half an hour 60 ÷ 2 = 30 km

(4) In three and half hours

= 3 x 60 + 30 

= 180 + 30 

= 210 km

∴ (1) 120 km

(2) 15 km 

(3) 30 km 

(4) 210 km
