Question

the speed of a car is 60 km / hr. It takes 3 hours to reach its destination. If the speed of the car is increased to 90 km / hr, how long will it take to cover the same distance.​

Answer 1

Answer:

speed = total distance traveled upon time taken

Step-by-step explanation:

= 90÷3 =30km/hr

Answer 2

Step-by-step explanation:

कार की चाल = 60km/hr

समय = 3 घंटे

चाल = दूरी / समय

दूरी = चाल * समय

= 60 * 3

= 180 km

यदि चाल 90 km/hr बढा़ दी जाएँ तो 180 km की दूरी तय करने में लगा समय = दूरी / चाल

=180 km/150km/hr

= 1.2 घंटे
