Question

36. A car, by going at the speed of 45 km per hour
reaches its destination in 4 hours. With what speed
can it reach there in 3 hours ?​

Answer 1

$\dag { \bold{AnswEr}}$

• Speed of car: 45 km/hr
• The time that is taken to complete journey: 6 hours
• Distance traveled: Speed x Time
• =45 x 6

• =270 kilometers

Speed needed to complete journey in 5 hours:

• (Speed x Time)/5
• = (45x6)/5

• = 270/5

• =54 km/hr

Therefore, the car needs to travel 54 km/hr to finish the journey in 5 hours.

Answer 2

Answer:

60 km per hour

Step-by-step explanation:

speed of car=45 km per hour

time taken to reach destination=4 hour

distance=speed×time taken

=45×4

=180km

speed of car to reach destination in 3 hour=180/3

=60km per hour
