Question

A jeep travels 180km in 4hours. If it travels the same distance in 3hours ,how much speed should it raise?

Answer 1

Answer:

15 km/hr

Step-by-step explanation:

Formula:

speed = Distance / Time

S= speed D = distance. T= time

now,

jeep travels 180 km in 4 hr

so its speed is given by,

S= D/T

S = 180/4

= 45 km/hr

now jeep travels same distance but it is in 3 hr

so its speed must be,

S= D/T

= 180/3

=60 km/hr

they asked how much it should be the speed to be raised,

before it was 45 and now its 60 so the speed raised by

60-45 = 15 km/hr
