Please solve this question

A person drives a car with a speed of 60km/hr and reaches his destination in 4 hours. If he decides to reach in 3 hours, what should be the speed ?

Answer 1

Answer:

80km/h

Step-by-step explanation:

distance=speed×time

60km/h×4h

=240km

now,

speed=distance/time

= 240km/3h

=80km/h

Answer 2

Ello

initial speed of car is 60 km/hr

time taken to reach its destination is 4 hrs

therefore, distance = (60 × 4) kms = 240 kms

if time is to taken as 3 hrs , and distance given is 240 kms

now,

speed should be = (240/3) kms/hr = 80 kms/hr
