A Car Covers Its Journey At The Speed Of 80km/hr In 10hours. If The Same Distance Is To Be Covered In 4 Hours, By How Much The Speed Of Car Will Have To Increase?

Answer»

Initial speed = 80km/hr

Total distance = 80 * 10 = 800KM

NEW speed = 800/4 =200km/hr

Increase in speed = 200 - 80 = 120km/hr.

Initial speed = 80km/hr

Total distance = 80 * 10 = 800km

new speed = 800/4 =200km/hr

Increase in speed = 200 - 80 = 120km/hr.
